8. A windscreen wiper device according to claim 2 , wherein said connecting device is connected to the flexible material of said wiper blade by one pin of the first type interconnecting said connecting device and said wiper blade near the middle longitudinal plane of said connecting device perpendicular to the windscreen to be wiped and by two pairs of opposite pins of the second type interconnecting said connecting device and said wiper blade near the outer ends of said connecting device.

9. A windscreen wiper device according to claim 2 , wherein said connecting device is connected to the flexible material of said wiper blade by one pair of opposite pins of the first type interconnecting said connecting device and said wiper blade near the middle longitudinal plane of said connecting device perpendicular to the windscreen to be wiped and by two pairs of opposite pins of the second type interconnecting said connecting device and said wiper blade near the outer ends of said connecting device.

10. A windscreen wiper device according to claim 2 , wherein said connecting device is connected to the flexible material of said wiper blade by one pair of opposite pins of the first type and by one pair of opposite pins of the second type interconnecting said connecting device and said wiper blade near the outer ends of said connecting device.

11. A windscreen wiper device according to claim 2 , wherein said connecting device is connected to the flexible material of said wiper blade by two pairs of opposite pins of the first type interconnecting said connecting device and said wiper blade near the outer ends of said connecting device.

12. A windscreen wiper device according to claim 11 , wherein the protrusions extend outwards on either side of said connecting device.

13. A windscreen wiper device according to claim 1 , wherein said connecting device is pivotally connectable with the oscillating arm with the interposition of a joint part, and wherein said joint part is detachably connected to said connecting device by engaging protrusions of said connecting device, at the location of said pivot axis, in recesses provided in said joint part.

14. A windscreen wiper device according to claim 13 , wherein said joint part has an at least substantially U-shaped cross-section at the location of its connection to said connecting device.

15. A windscreen wiper device according to claim 13 , wherein said protrusions are provided with co-axial through holes.

16. A windscreen wiper device according to 13 , wherein said joint part comprises at least one resilient tongue engagable within a correspondingly shaped hole provided in a base of a U-shaped cross-section of the oscillating arm, and wherein said resilient tongue is rotatable along a hinge axis between an outward position for retaining said wiper blade onto the oscillating arm and an inward position for releasing said wiper blade from the oscillating arm.

17. A windscreen wiper device of the flat blade type, comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove, in which groove at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein the oscillating arm can be pivotally connected to said connecting device about a pivot axis near one end thereof, wherein said connecting device is connected to the flexible material of said wiper blade by at least one pin, wherein said pin cooperates with a recess provided along an exterior edge of said longitudinal strip in order to block any movement of said wiper blade in longitudinal direction thereof relative to said longitudinal strip at the location of the interconnection of said connecting device and said wiper blade wherein said connecting device is connected to the flexible material of said wiper blade by said at least one pin being of a first type and at least one pin of a second type, wherein said pin of the second type is slightly deforming said wiper blade at the location of the interconnection of said connecting device and said wiper blade in order to block any lateral movement of longitudinal strip at the location of the interconnection of said connecting device and said wiper blade, wherein said pin of the second type is of a softer material than the flexible material of said wiper blade in order not to damage the flexible material of said wiper blade.

18. A windscreen wiper device of the flat blade type, comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one longitudinal groove, in which groove at least one longitudinal strip of the carrier element is disposed, which windscreen wiper device comprises a connecting device for an oscillating arm, wherein the oscillating arm can be pivotally connected to said connecting device about a pivot axis near one end thereof, wherein said connecting device is connected to the flexible material of said wiper blade by at least one pin, wherein said pin cooperates with a recess provided along an exterior edge of said longitudinal strip in order to block any movement of said wiper blade in longitudinal direction thereof relative to said longitudinal strip at the location of the interconnection of said connecting device and said wiper blade, wherein said connecting device is connected to the flexible material of said wiper blade by said at least one pin being of a first type and at least one pin of a second type, wherein said pin of the second type is slightly deforming said wiper blade at the location of the interconnection of said connecting device and said wiper blade in order to block any lateral movement of longitudinal strip at the location of the interconnection of said connecting device and said wiper blade, wherein said pin of the second type is inserted in a tube of a softer material than the flexible material of said wiper blade in order not to damage the flexible material of said wiper blade.
