Abstract

An unlocking prevention device for a steering wheel lock of that type having a driver acting on a detent pin and controlled by a locking cylinder shaft. During the unlawful removal of the locking cylinder, the shaft is shifted in its pull out direction by means of a force and the driver thereby engages into a groove, as a result of which the shaft cannot be removed and, because of the changed form of the shaft, the driver can no longer be actuated.
