Abstract

The invention relates to a valve, especially a return flow blocking valve for a drinking water supply, comprising a housing (7), which has a maintenance opening (8), and a lid (9), which covers said maintenance opening. The lid (9) is connected to the housing (7) by a bayonet-type connection. The aim of the invention is to provide a releasable connection with simple means for ensuring its stability. To this end, one of the two lid (9) and housing (7) parts has at least two fixing plates (15, 16) which extend radially and in the peripheral direction in relation to the maintenance opening (8), and the other part has a corresponding number of fixing devices (17, 18) which are open at the side in the peripheral direction. These fixing devices encompass the fixing plates (15, 16) in a U-shape.
