Sanitary body like a sink, etc. or a worktop.

In contrast, the fitting housing can be easily detached from the valve holder, wherein at the same time one or more

Shut-off valves shut off or lock the water pipes. Accordingly, the water pipes are opened at the same time when connecting the valve body to the valve holder.

These fittings, for example, allow maintenance or repair of individual components of the fitting, such as e.g.

Mixing valve, dirt filter or electrical fittings also a replacement of batteries / rechargeable batteries or more

electrical components, without water leaking from the lines and without the usually below the

Washbasin arranged angle valves of the water supply lines must be closed.

This is advantageous because e.g. in baths or the like such angle valves are not (easily) accessible or not available. The latter applies especially in the

CONFIRMATION COPY public or semi-public space where such

Corner valves could be manipulated or even damaged by vandalism.

Especially for applications in public or

semi-public space, however, are initially mentioned easily removable fittings just because of the problem

Vandalism can not be used as they would be damaged or even removed within a short time.

The object of the invention is to propose a sanitary fitting of the type mentioned, which can be maintained or repaired with very little effort, especially in

Applications where the requirements regarding
