ABSTRACT:
The invention relates to a sanitary safety device which is interposed in a water-supply line and there is insertable in an opening in the region of a coupling point or joint. It is characteristic of the sanitary safety device according to the invention that the sanitary safety device has a flow regulator (2) or similar restrictor as well as a backflow preventer (3), these being combined in the sanitary safety device to compose a constructional unit in the form of a cartridge (1). Such is insertable for example, in the opening of a recess in the form of a cartridge mount provided in a hose connector. The cartridge (1) composed of the flow regulator (2), backflow preventer (3) and any strainer attachment (8) at the inflow end can thus be interposed in a water-supply line in a simple fashion and with little effort.
