A steering column includes a jacket tube with a clamping section with a slot extending longitudinally. A clamping collar has transversely opposed legs are interconnected via an arcuate section between which the clamping section of the jacket tube is at least partially accommodated. An actuating unit is arranged in the jacket tube, with a steering spindle rotatably mounted therein around the longitudinal axis. A clamp fixes the actuating unit longitudinally relative to the jacket tube and in a release position unclamps the clamping collar and frees the actuating unit longitudinally and presses the legs toward each other transversely to the longitudinal axis in the fixing position. Driver elements are arranged on the jacket tube in opposite edge regions of the slot, and the legs include contact elements which in the fixing position can be pressed against the outer sides of the driver elements.
