Device for locking a steering column of a vehicle

A device for locking a steering column of a vehicle, comprising:

• a force-loaded locking member;
• a control device configured to adjust the locking member relative to the steering column between a locking position preventing rotation of the steering column and a release position allowing rotation of the steering column;
• wherein the locking member is comprised of one or more clamping jaws having a substantially smooth friction surface without profile;
• a substantially smooth counter friction surface without profile provided on the circumference of the steering column;
• a force generator connected to the control device, wherein the force generator is configured to exert in a locking situation, where the locking member is in the locking position, a clamping force onto the locking member directed against the counter friction surface and is configured to turn off the clamping force in a release situation where the locking member is in the release position.
