A device serving as a coupling between a flexible pipe conduit (1) installed underneath plaster and a fitting arranged above the plaster comprises a casing (4, 5a, 5b, 6) and a pipe elbow (3) insertable in the casing (4, 5a, 5b, 6) and fixable therein. The casing is fashioned so that the pipe elbow can be connected to the pipe conduit (1) in two different ways. In one type of mounting, the inner pipe (1) is bent out of the wall, the pipe elbow (3) is attached thereto, and the entire arrangement is then placed into the casing (4). In the second type, the pipe conduit is connected to the pipe elbow (3) which latter is inserted in the casing head (4) and attached therein. The casing neck consists of two half shells (5a, 5b) encompassing the clamping ring closure (10) projecting in the downward direction from the casing head (4), as well as a section of the pipe conduit (1 ). The casing neck fixedly clamps the outer pipe (2) in place and thereby prevents slipping out of this outer pipe.
