<p>A connection assembly for a waste disposal unit comprises a stainless steel, open-ended tubular sink bush (35), which can be retained in a sink outlet hole by means of its flanges (36), a plastics material hopper (12), a lock ring (30), and a rubber seal (24). An end of the sink bush (35) has an annular groove (37) in its outer surface for engagement with a corresponding annular projection (25) on the internal surface of the hopper (12). Slots (28) divide one end of the hopper into flexible fingers (29) which allow the sink bush to be fitted in the end of the hopper as a snap-fit. Once the lock ring (30) is screwed up around the fingers (29) the hopper and sink bush are securely connected. The seal (24) is compressed by an end of the sink bush (35) and prevents leakage between the hopper and sink bush. <IMAGE></p> |
