A telescopable, height-adjustable steering column for power vehicles comprises an inner pipe provided with a sliding surface, an outer pipe provided with a sliding surface cooperating with the sliding surface of the inner pipe. One of the pipes is displaceable relative to the other of the pipes. An element for closing the tolerance gap between the sliding surfaces of the inner and outer pipes and includes two wedge members located between the pipes and displaceable under a spring action transversely to an axis of the steering column over two inclined planes.
