Abstract: The invention relates to a device for blocking the rotary movement of a steering column (1) in a motor vehicle by means of a blocking bolt (5) which is actuated by a lock and in the blocking position engages in a recess (4) in the steering column. At least one further blocking bolt (6) is provided which can be actuated by the same lock and, like the first blocking bolt (5), in the blocking position engages in recesses (4) arranged at regular spacings around the periphery of the steering column. Material located between the recesses (4) forms, as protrusions (3), side faces (Z) for blocking the blocking bolts (5, 6).
