Abstract
Abstract A steering lock for motor vehicles consisting essentially of a steering lock housing, a lock cylinder, a rotor with plate tumblers, a cover cap with a cylindrical extension and a locking pin forced outwardly by a spring and extending through the steering lock housing, which engages in a groove provided in the extension of the cover cap; this extension is thereby made from a material of high strength and an immersion aperture is provided at the end face of at least one plate tumbler, into which the locking pin can be inserted in such a manner that it also simultaneously overlaps over at least one plate tumbler.
