The clamping disk 38 is displaceable along the guide 37, which extends partially circumferentially along a circumferential surface of the telescopic piece 33. The space 40 present between the telescopic piece 33 and the wash basin 3 can be successively reduced by moving the clamping disc 38 until the clamping disc 38 contacts the wash basin 3. For this purpose, the guide 37 and the clamping disk 38 form two wedges, through the mutual displacement of which a possibly differently existing free space 40 can be bridged.
