the first bridle is provided with a second eyelet formed therethrough, said second eyelet being located, along the first bridle, at a longer distance from said first fastening of the locking pin than the distance between the first eyelet and said first fastening of the locking pin to the first bridle is,

from said second fastening of the locking bridle to the locking pin, the locking bridle passes:

first through the second eyelet, towards a second side of the first bridle opposite to a first side of the first bridle,

then through the fastening loop,

and then, in an opposite direction, through the first eyelet, and,

said fastening loop fastened to the second bridle can slide freely along said second side of the first bridle, between the first and second eyelets.

2. The device according to claim 1 , wherein after being passed through the fastening loop, the locking loop of the locking bridle passes directly through the first eyelet.

3. The device according to claim 1 , wherein, in a state of the locking pin passed through the locking loop, the first bridle exhibits a fold having two facing flaps and located between the second eyelet and the location of the fastening of said locking pin to the first bridle, and no means for maintaining said fold is provided between the two facing flaps thereof.

4. The device according to claim 1 , wherein in a state of the locking pin passed through the locking loop, the locking bridle is positioned on a flap adapted to come over a storage space of a harness bag which receives a reserve deployment bag in which the reserve parachute is folded, said locking bridle thus being positioned by means of a leg engaged in a pocket of the flap.

5. The device according to claim 4 , wherein said leg is fastened to the fastening loop in which passes the locking bridle.

6. The device according to claim 1 , wherein, in a state of the locking pin passed through the locking loop, the first bridle fastened to said locking pin is positioned on a flap adapted to come over a storage space of a harness bag which receives a reserve deployment bag in which the reserve chute is folded, by means of a self-gripping strip in two portions respectively provided on the flap and the first bridle.

7. The device according to claim 1 , wherein an elastic return means under which passes the locking pin when it is engaged in the locking loop presses the locking pin on the first bridle by maintaining said locking pin.

8. The device according to claim 7 , wherein the locking pin ends at one end with a closed ring with which it is fastened to the first bridle and the elastic return means is an elastic band arranged to cover said closed ring when the locking pin is engaged in the locking loop.

9. The device according to claim 1 , wherein at the location where the locking pin is engaged in a releasable manner in the locking loop, the first bridle is provided with a structural reinforcement.

10. The device according to claim 1 , wherein the locking pin exhibits at one end a closed ring which extends in a substantially tangential manner by an extended portion around which the locking loop passes.

11. The device according to claim 1 , wherein the fastening loop is in the form of a bridle loop in which passes the locking bridle, and the fastening loop of the second bridle comprises a closed metal ring.

12. A parachute device comprising:

a main parachute,

a reserve parachute connected to a pilot chute and a deployment bag,

a releasing device for releasing the main parachute and opening the reserve parachute, the releasing device comprising:

a first bridle fastening the pilot chute to the deployment bag,

a second bridle fastening the main parachute to the first bridle, and,

a locking pin,

a locking bridle having a locking loop,

a first fastening for fastening the locking pin to the first bridle, on a first side thereof, said locking pin passing, in a free manner, in the locking loop,

a second fastening for fastening said locking bridle to the locking pin,

a fastening loop fastened to the second bridle, towards an end thereof, and,

a first eyelet formed through the first bridle,

wherein:

the first bridle is provided with a second eyelet formed therethrough, said second eyelet being located, along the first bridle, at a longer distance from said first fastening of the locking pin than the distance between the first eyelet and said first fastening of the locking pin to the first bridle is,

from said second fastening of the locking bridle to the locking pin, the locking bridle passes:

first through the second eyelet, in a first direction, towards a second side of the first bridle opposite to a first side of said first bridle,

then through the fastening loop,

and then, in a second direction opposite to the first one, through the first eyelet, and

the fastening loop fastened to the second bridle can slide freely along said second side of the first bridle, from the first eyelet and to the second eyelet and conversely.

13. A parachute device comprising:

a main parachute,

a reserve parachute connected to a pilot chute and a deployment bag,

a releasing device for releasing the main parachute and opening the reserve parachute, the releasing device comprising:

a first bridle fastening the pilot chute to the deployment bag,

a second bridle fastening the main parachute to the first bridle, and

a locking pin,

a locking bridle having a locking loop,

a first fastening for fastening the locking pin to the first bridle, on a first side thereof, said locking pin passing, in a free manner, in the locking loop,

a second fastening for fastening said locking bridle to the locking pin,

a fastening loop fastened to the second bridle, towards an end thereof, and,

a first eyelet formed through the first bridle,

wherein:

the first bridle is provided with a second eyelet formed therethrough, said second eyelet being located, along the first bridle, at a longer distance from said first fastening of the locking pin than the distance between the first eyelet and said first fastening of the locking pin to the first bridle is,

from said second fastening of the locking bridle to the locking pin, the locking bridle passes:

first through the second eyelet, in a first direction, towards a second side of the first bridle opposite to a first side of said first bridle,

then through the fastening loop,

and then, in a second direction opposite to the first one, through the first eyelet, and,

the locking bridle extends continuously from the locking loop to the second fastening, so that the fastening loop fastened to the second bridle can slide freely along said second side of the first bridle, from the first to the second eyelets and conversely.
