The lower part (6) of the support tube (2), ie. the actual support bell, has at its upper end an outwardly directed flange edge or an outer bulge (10). One end (14) of the roller bellows after flanging the widened lower end (8) of the upper support tube part (4) is clamped between the latter and the flange edge or bulge at the upper end of the lower support tube part (6). The outer edge of the outwardly pressed flange edge of the lower part of the support tube is bent inwards. The two support tube parts comprise galvanised or otherwise coated steel plate, or can be made of different materials.
