A rotatable coupling assembly for facilitating the connection and separation of a waste discharge hose between a recreational vehicle waste discharge outlet and the inlet of an external waste disposal receptacle, including a first coupling with a first fitting having a generally cylindrical main body with a flanged portion. A second fitting is also provided and is adapted to slide along the main body until it approaches the first fitting. The second fitting has radial projections for lockingly engaging corresponding hook-like members of a mating fitting of a second coupling, or the converse. A similarly structured third or mating fitting is also provided. A flanged ring member with an annular seating surface joins with one end of the discharge hose to enable the mated components to be slidably disposed along the main body until they approach the second fitting. When the parts are engaged, as described, the second fitting, which, in one example, comprises radial projections in one coupling and the third fitting, which comprises mating hook-like members in the other coupling, may each freely rotate about the corresponding main body.
