ABSTRACT:
A snap-hook comprises a pivoting finger with a rotary locking ring cooperating with a locking bolt. This bolt has an operating component designed to cooperate alternately with a hole or a notch arranged in the locking ring with a preset angular offset, respectively in the first locked position to perform said positive locking of the ring in rotation when the operating component is inserted in the hole, and in a second unlocked position with formation of an internal link with a hang-up between the ring and finger when the operating component engages in the notch, moving from the second unlocked position to the first locked position being performed manually by a rotational movement of the ring causing the hang-up to be released at the beginning of travel following the reaction of the ring on the operating component, and insertion of the operating component in the hole at the end of travel for positive locking of the ring in rotation.
