Abstract

A locking device for a motor vehicle having a steering column has a blocking bolt that locks the steering wheel shaft in the steering wheel column, wherein the blocking bolt is movable between a first and a second position, a return element that returns the blocking bolt to the first position, and at least one protection cover that at least partially covers the return element. In the first position, the blocking bolt is in blocking engagement with the steering wheel shaft. In the second position, the blocking bolt is disengaged from the steering wheel shaft. The return element is a torsion spring. The torsion spring is a coil spring with a coil body and a connection hook. A first end portion of the torsion spring has a hook extension, and is inserted into an opening of the blocking bolt and is covered at least partially by the blocking bolt.
