A support tube adapted to carry a motor-vehicle accessory and to slide in a bearing tube provided with a latch element is hollow, cylindrical, centered on an axis, and formed with a plurality of outwardly open notches. These notches are each in turned formed by a flat latch face extending generally perpendicular to the axis, an outwardly open indent adjacent the latch face, a cam face extending from the latch radially outward to an outer surface of the tube, and a flat base face extending generally parallel to the axis from an inner edge of the latch face to an inner edge of the cam face.
