an axial cavity that runs offset and parallel to the axis of the barrel member,

a radial cavity intersecting with the axial cavity and having a width larger than that of a head of said locking stub,

a slot disposed transverse to said barrel member and communicates with said axial and radial cavities, and wherein said slot includes a width larger than that of a rod of said locking stub but less than that of the head of said locking stub,

an annular recess disposed into a circumference of said barrel in which a set screw is engaged, thereby allowing the rotation of said barrel by a fraction of one revolution.

2. An automated spraygun as claimed in claim 1 , wherein

said rod having has a diameter and the width of the head exceeds the diameter of said rod.

3. An automated spraygun as claimed in claim 1 , wherein said foundation comprises

a receptacle into which said locking stub is to enter; and

a cavity in which said barrel member is configured substantially perpendicular to and intersects with said receptacle.

4. An automated spraygun as claimed in claim 1 , wherein said barrel member for said locking stub comprises at least one ramp adapted to rest against a base of said head of the stub and defined by a thickness variation in said barrel member for enabling pulling said locking stub.

5. An automated spraygun as claimed in claim 1 , wherein the barrel member is cylindrical and further comprises a keying means for preventing translational movement of said barrel.

6. An automated spraygun as claimed in claim 1 , wherein said positioning means at least comprise one centering pin configured in a manner to perpendicularly project from one of said rest and seating faces and adapted to enter at least one receptacle on the other of said rest and seating faces by translating perpendicularly to said rest and seating faces.

7. An automated spraygun as claimed in claim 1 , further comprising:

at least one tubular socket adapted to enter the junction between one of the first feed conduits of the spraygun body and the respective second feed conduit of the foundation, said tubular socket comprising a first portion adapted to enter the first orifice of said first feed conduit and a second portion adapted to enter the second orifice of said respective second feed conduit.

8. An automated spraygun, comprising:

a spraygun body including

a plurality of first feed conduits for feeding a product to be sprayed and a pressurized gas, and

a rest face into which said first feed conduits issue in the form of first orifices;

a foundation including

a seating face which said rest face is to be forced against,

a plurality of second feed conduits that are complementary to said first feed conduits and terminate, on one hand, into connection elements to spray product and pressurized gas feeds and, on the other hand, into second orifices in said seating face,

said first and second orifices being configured in a manner that each first rest orifice coincides with a respective one of the second orifices when said rest face of the spraygun body is forced against said seating face of the foundation;

seals to be inserted between said seating face and said rest face and peripherally located at each junction between the respective first and second orifices;

a positioning member for positioning said spraygun body on said seating face, said positioning member projecting perpendicularly from one of said rest and seating faces and translating orthogonally into the other of said rest and seating faces in a manner to position said rest face relative to said foundation face in a plane;

a locking stub projecting perpendicularly from one of said rest and seating faces and orthogonally translating into the other of said rest and seating faces; and

a locking member rotatable about an axis substantially perpendicular to said locking stub, wherein the rotation of said locking member about said axis translates into an axial pull on said locking stub to force said rest and seating faces against each other;

wherein said axial pull is sufficient to compress the seals between the rest and seating faces for sealing against leakage of the product to be sprayed and the pressurized gas at the junctions of the respective first and second orifices,

wherein said locking member comprises

a circumference,

an axial cavity that runs offset and parallel to the axis of the locking member,

a radial cavity intersecting with the axial cavity and having a width larger than that of a head of said locking stub,

a slot disposed transverse to said locking member and communicates with said axial and radial cavities, said slot includes a width larger than that of a rod of said locking stub but less than that of the head of said locking stub, and

an annular recess disposed into the circumference in which a retaining member is engaged, thereby allowing the rotation of said locking member by a fraction of one revolution.

9. An automated spraygun, comprising:

a spraygun body comprising a rest face on which at least a first orifice of a first conduit is formed;

a foundation comprising a seating face on which at least a second orifice of a second conduit is formed corresponding to the first orifice so that the first and second conduits define a path for feeding a product to be sprayed or a pressurized gas;

a seal between said seating and rest faces for sealing a junction between the first and second orifices;

a locking rod projecting from one of said spraygun body and foundation into the other of said spraygun body and foundation; and

a locking member rotatable about an axis substantially perpendicular to said locking rod, wherein the rotation of said locking member about said axis translates into an axial pull on said locking rod to force said rest and seating faces against each other with a force sufficient to compress the seal between the rest and seating faces to seal against leakage of the product to be sprayed or the pressurized gas at the junction of the first and second orifices,

wherein said locking member comprises

a circumference,

an axial cavity having an axis that runs offset and parallel to the axis of the locking member,

a radial cavity intersecting with the axial cavity and having a width larger than that of a head of said locking stub,

a slot disposed transverse to said locking member and communicates with said axial and radial cavities, said slot includes a width larger than that of a rod of said locking stub but less than that of the head of said locking stub, and

an annular recess disposed into the circumference in which a retaining member is engaged, thereby allowing the rotation of said locking member by a fraction of one revolution.

10. An automated spraygun as claimed in claim 9 , further comprising:

a positioning element for aligning the first and second orifices and restricting relative motion between said spraygun body and foundation to translational movements along a pulling direction in which said rest and seating faces are forced against each other.

11. An automated spraygun as claimed in claim 10 , wherein said locking member comprises a surface inclined with respect to the pulling direction for increasingly pulling the locking rod, hence the other of said spraygun body and foundation, toward said one of said spraygun body and foundation as the locking member is rotated.

12. An automated spraygun as claimed in claim 9 , wherein said locking rod comprises a shank and a head having a larger width than said shank.

13. An automated spraygun as claimed in claim 9 , wherein

said locking member is detachably mounted on one of said spraygun body and foundation to be rotatable about an axis while being secured against displacement along said axis by engagement of said locking member with said locking rod; and

said locking member is displaceable along the axis relative to said one of said spraygun body and foundation when said spraygun body is not mounted on said foundation.
