ABSTRACT:
A coupling arrangement for tubes, pipes or like members in a washing machine comprises one or more tubes provided with a ring packing on one end thereof, a coupling member on the machine, and a clamping device for engaging the tube. The ring packing is formed in three integral portions including a slide ring portion for guided axial displacement, an elastically axially compressible central part and an axially fixed supporting ring. The coupling arrangement is assembled by an insertion of the slide ring portion into an opening in the coupling member and pressed therein by the clamping device which first stresses the central part and urges it toward the coupling member and thereafter allows a slight backing away of the central part away from the coupling member. The slide ring portion is formed with a conical end surface for reception in and cooperation with the coupling member of which the opening is formed with a corresponding or mating surface to maintain a light seal.
