A burglar-proof device for a lock with swivel bolt, wherein the bolt (18) is articulated in the lock case (2,3) and is rotatable, by means of a plate (30) actuated by the plug (32) of a cylinder (32a), between a position in which it is inside the case (2,3) and a position in which it is outside the case (2,3) and engages a selvage. A pawl (45) is articulated in the case (2,3) and cooperates with the plate (30) so that, when the plate (30) has actuated the bolt (18) into the external position, the pawl (45) is in a bolt blocking position, whereas when the plate (30) is actuated to move the bolt (18) into the internal position, the pawl (45) is first actuated into the bolt release position by the plate (30). <IMAGE> |
