ABSTRACT:
A flexible pipe coupling is constructed for flexibly interconnecting pipe sections especially in a vacuum toilet system on board an aircraft. For this purpose each coupling member of a pair forming the coupling has a bushing for connection to a pipe end by a hose clamp, a flange integrally connected to the bushing, and a support ring for backing the respective flange but permitting the flange to retain a certain flexibility. Each support ring has a conical circumferential rim. The coupling also includes a clamp member encircling with radially inwardly facing conical surfaces the radially outwardly facing conical rim of both support rings to clamp the coupling members together. The clamp member has a threaded or snap device for applying the clamping force.
