A bathroom waste collection and disposal unit for mounting on a floor of an enclosure includes a tank of unitary construction having a horizontal portion defining a refuse reservoir and a vertical portion open to the horizontal portion for refuse gases and to accommodate a pump. A toilet is mounted on the top surface of the horizontal portion in fluid communication with the reservoir of the horizontal portion of the tank. The horizontal portion includes a plurality of columns within the reservoir extending between the floor and top wall of the horizontal portion. The tank also includes a baffle housing for enclosing the float of the refuse pump to meter the rate of flow of water flowing away from the pump float as the pump is actuated to discharge refuse from the reservoir.

A snap-in fitting includes male and female connector elements which are connectable to fluid conduits. The male connector element is insertable within a socket of the female connector element and is retained therein by a coupling ring. The coupling ring includes an integral base portion, collar portion and locking portion. The collar portion is seated within a retaining channel of the male connector element, and the locking portion lockingly abuts within a locking groove of the socket. The collar portion includes annular surfaces which converge from the base portion. The locking portion extends outwardly at an angle from the base portion and includes annular surfaces which diverge from the base portion. An undercut is formed at the juncture of the locking portion with the base portion, to maintain the pivot point of the locking portion adjacent such juncture. An O-ring mounted on the male connector element sealingly engages a wall of the socket. The configuration of the locking ring assures that inward and outward pivoting of the locking portion during merging of the male and female connctor elements occurs at the region where the locking portion joints the base portion. This enhances maximum radial entry of the locking member into the locking groove even when the ring is formed of relatively stiff material. The female connector element includes an adapter portion and a retaining sleeve portion which are threadedly secured together, and which each include means cooperating to define the sleeve and locking groove of the socket. By decoupling the adapter and retaining sleeve the connection can be disassembled without removing the female connector element from its associated fluid conduit.

A pipe coupler assembly comprises a fitting which is securable to the ends of a pair of pipes. The fitting comprises a socket portion for receiving the pipe end. A plurality of tabs project rearwardly and outwardly from the socket portion and are disposed in circumferentially spaced relationship about a longitudinal axis of the fitting. The fitting also includes a circumferentially extending, radially outwardly open channel disposed forwardly of the socket portion. The channel extends radially inwardly relative to the socket portion and is adapted to receive a resilient seal ring. A generally radially extending shoulder is disposed between the tabs and the channel. This shoulder is adapted to engage an edge of the pipe end to limit insertion of the fitting. The assembly also includes a generally cylindrical, open-ended sleeve. The sleeve is sized to receive the fittings through axially aligned chambers thereof. The fittings are insertable into the chambers, with the tabs being initially inwardly flexed and then springing into securing engagement with recesses in the chambers, and with a seal ring in the channel being compressed sealingly against the chamber walls.
