The siphon (20') has a curved suction housing (22), which is closed at one side by a suction disk (24). A cavity (40) is formed between the suction housing and the suction disk. A tension lever (26) is provided for reducing a spacing between the suction housing and the suction disk for producing a suction effect. A ring-shaped sealing flange (10) is fixed on the suction disk, which has an internal groove (18) on the sealing flange, in which the suction disk is inserted with its outer edge (34) and elastic sealing surface (16) for abutment against the surface (38) of the object (36). |
