Abstract: A sanitary appliance (1) has a location space (3), which is cut out of a housing (2) and intended for a cartridge (4) containing the control elements. A base (6) closes off the location space (3) in a downward direction. A water supply pipe (11) is detachably fastened in a bore (25) of the base (6). The water supply pipe (11) is axially locked by a conical tension spring (21) disposed in a location space (19) of the base (6). The tension spring (21) is applied by its smaller-diameter end with frictional engagement against the outer surface of the water supply pipe (11). With its larger-diameter end the tension spring (21) is supported against the base of the location space (19). The conical lateral surface of the tension spring (21) widens towards the outer end of the water supply pipe (11). In said manner, smooth water supply pipes may be fastened through simple insertion into the otherwise already completely assembled sanitary appliance.
