    • A clamping device for an adjustable steering column for a motor vehicle comprises a clamping bolt which is rotatable about its longitudinal axis for the opening and closing of the clamping device by means of an actuation lever, through an opening of which the clamping bolt extends. In the region of the opening of the actuation lever there is situated a connecting section of the clamping bolt, over the axial extent of which connecting section the clamping bolt is connected to the actuation lever by way of a press fit. The outer wall of the clamping bolt has, in the connecting section of the clamping bolt, at least two pressing regions which are spaced apart in the circumferential direction about the longitudinal axis and by way of which the actuation lever is pressed against the outer wall.
