The invention relates to a lock for locking at least one movable element (1).
The lock according to the invention comprises a rocker (7) pivoting about a spindle and returned elastically towards a rest position in which it does not lock the said movable element (1), a cylinder (6) rotatable under the action of a key and controlling the said rocker (7) in the course of its rotation in order to bring it into a second position in which it locks the said movable element (1), the key being withdrawable from the cylinder (6) for a locking position and an unlocking position of the rocker (7), a plurality of rotating serrated wheels (3, 4) each co-operating with the said rocker (7) to bring it to the said second position with the exception of one angular position of each serrated wheel (3, 4) in which the latter does not co-operate with the rocker (7), a slide piece (22) co-operating with the serrated wheels (3, 4) and the cylinder (6) and being able to occupy a first position in which it locks neither the cylinder (6 ) nor the serrated wheels (3, 4), and a second position in which it locks the serrated wheels (3, 4) in rotation.
