This present application concerns a boundary box for a tap that can be mounted in the wall. The boundary box comprises a housing (3) and a fixture frame (1) which is slidable mounted on the housing. The position of fixture frame can be fixed using a linkage mechanism whereby a first notch (7) on the inner side of the frame facing the housing interacts with a first rib (4) on the outer wall of the housing. The frame is provided with a passage (6) extending from the outer side of the frame to the inner side. The passage ends in the notch. The boundary box further comprises a plug (2) that can be inserted in the passage such that the plug cooperates with the rib on the housing and fixes the position of the frame relative to the housing.
