A coupling part 2 mounted in a sink top, work surface or similarly arranged equipment is designed for replaceable connection of different types of single-hole mixing battery 1. The connection part 1a of the single-hole mixing batteries 1 has a screw or a hole which allows operation of a screw 4 which is arranged in the coupling part 2 and, on tightening, brings about an axially directed force, by means of which the mixing battery is pressed against the support 10. For this purpose, the screw can, if appropriate, act on a flanged locking ring 6 provided with an inclined surface which, when the flange ring is displaced to an eccentrically located position, enters into engagement with the edge of a groove 1d formed in the connection part 1a. In this way, a safe and reliable mounting of a single-hole mixing battery 1 on a coupling part 2 is achieved, with the desired sealing of delivery and return pipes there at the same time as simple replacement of the mixing battery is allowed, and considerable cost-saving and simplification is achieved in production and stockholding as well as sales. <IMAGE> |
