Sanitary appliance
First Claim
1. A sanitary appliance havinga) a housing;
- b) a region cut out of the housing spaced from a cartridge containing control elements;
c) a base closing off the region in a downward direction;
d) at least one water supply pipe fastened detachably in a bore of the base, and e) axial locking means for the water supply pipe, wherein f) the axial locking means comprise a conical tension spring, which is disposed in the region, is applied by its smaller-diameter end with frictional engagement against the outer surface of the water supply pipe and is supported by its larger-diameter end against the base in the region;
wherein g) the lateral surface of the conical tension spring widens towards the outer end of the water supply pipe, h) the water supply pipe being inserted with a low force into the sanitary appliance, the water supply pipe being secured in the sanitary appliance by the conical tension spring, the conical tension spring having a retaining force that increases against the water supply pipe in response to a pulling motion, and the water supply pipe being withdrawn from the sanitary appliance with a force larger than said low force required to insert the water supply pipe into the sanitary appliance.

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.
