The invention deals with a lock made up of a box-like structure (1) whose frontal face brings a slot (2) for the insertion of an actuating plaque (3). A set of holes (4) is made on the plaque the function of which is the different sliding of the pins (18), when the plate is inserted. The pins (18) are hosted into the hollows of an internal dowel (12). From the body of the pins (18) teeth (20) jut out. The height from which they stick out is not the same. But when the plaque (3) inserted is the right one, it pushes the heads (19) of the pins (18) each one of the needed quantity to make the teeth (20) align. This way the teeth (20) can slide into the longitudinal groove (10) and this makes possible the movement of the dowel (12). Since the dowel (12) is linked with a bar (14) that juts out from the box (1), through a rectangular opening (7) on the rear side, this bar (14) slides, dragged by the single movement of the plaque (3), pins (18) and dowel (12) and it makes the lock change its state from open to closed and vice versa. <IMAGE>
