ABSTRACT:
A cylinder lock, especially for motor vehicles, consisting of a rotor with tumblers, which is operatively connected with locking elements; with a key pulled off in the locking position, the tumblers engage in a tumbler channel provided in the inner wall of a stator receiving the rotor; a cut-in or groove constructed as intentional breaking or rupturing place is provided in the rotor adjoining the last tumbler, as viewed in the key insertion direction, which ruptures when a springily engaging locking action between the rotor and the stator not accessible from the outside has taken place during a forcible pulling out of the rotor.
