ABSTRACT:
A device is provided formed by a case which contains, on each side of a ball for retaining the coupling member of the belt, two spring-loaded sliding keys cooperating alternately with the ball so that the retreat of one against the action of its spring allows the automatic advance of the other one either for locking said ball in the coupling member of said belt during penetration of this member into the case, or for releasing said coupling member and automatically ejecting same, depending on the key which is moved back against the action of its spring.
