The invention relates to a telescopic shaft, in particular for floor-cleaning appliances, with a handle-operated locking pin (10, 11) which is arranged in a fixed position relative to the telescopic outer tube (4, 5) and, as a result of spring loading, enters through an opening (17) in the wall of the telescopic outer tube (4, 5) into one of several insertion holes (9) in the telescopic inner part (6, 7). The invention, in particular to facilitate the handling, proposes that the operating handle, designed as rotary knob (20) and releasing the locking pin (10 or 11) for spring-loaded entry into the locking position, has a peripheral control step (27) which in the locking position moves a clamping lever (28 or 29) into the braking position relative to the inner part (6 or 7) so that, when the interlocking is released, a brake is also released, which in the catch position takes up any play between the two telescopic parts. <IMAGE>
