ABSTRACT:
A connector for coupling a hose to a faucet or the like includes two molded plastic members which are coupled together by a bayonet-type connection. One member carries a resilient seal which has an annular lip inclined radially inwardly and axially toward an axially facing annular sealing surface on the other member. When the members are coupled, the lip flattens against the sealing surface to form a seal between the members and, in this condition of the parts, the resiliency of the lip also produces a force which keeps the bayonet-type connection in the locked position. When the members are being coupled while water is running through the member with the seal, an annular groove in the sealing surface causes water to backwash and clean the sealing side of the lip as well as the sealing surface itself.
