Abstract

In a fitting for water conduits having a back-siphonage prevention device (104) and shut-off means for shutting off the flow of water upstream and downstream of the back-siphonage prevention device, the shut-off means are formed by a piece of tube (82) which is axially adjustable in a fitting housing and accommodates the back-siphonage prevention device (104) and the interior of which is connected in an open position, via a lateral opening (100) arranged upstream of the back-siphonage prevention device (104), to an inlet and, via a lateral opening (102) arranged downstream of the back-siphonage prevention device (104), to an outlet, while the lateral openings (100, 102) are covered over in a closed position of the piece of tube (82). <IMAGE>
