This buckle comprises, housed in a casing (1), a body (4), a member for locking (5) a bolt, a sliding block (10) mounted in the body so as to be capable of travelling in the direction of travel of the bolt and which cooperates with a spring (12) for ejecting the bolt, another spring (16) pressing the locking member towards its position in which the bolt is locked, and a member for producing (6) unlocking for moving the locking member towards its position in which the bolt is unlocked. The sliding block (10) is mounted so that it can travel between a forward position, in which a first bearing surface of the locking member (5) bears against the sliding block (10), corresponding to the position in which the bolt is unlocked, and a rear position, in which the locking member has oscillated relative to the body so that a second bearing surface of the locking member bears against this sliding block, this rear position of the sliding block corresponding to the position in which the bolt is locked.
