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.

A connector for hoses and the like having, in combination, a first tubular member having an inlet end portion and a first sealing end portion, a second tubular member having an outlet end portion and a second sealing end portion opposing said first sealing end portion, one of said members having a cylindrical skirt encircling and projecting axially beyond the sealing end portion of that member and the other of said members having a cylindrical sleeve encircling and extending beyond the sealing end portion of that member, said sleeve telescoping with said skirt, said members having alined axial passages for the flow of pressure fluid from said inlet end portion to said outlet end portion, an axially facing annular sealing surface formed on the sealing end portion of said second member and encircling the passage in that member, said surface facing said inlet end portion of said first member, a cylindrical sealing element of resilient material carried by the sealing end portion of said first member and encircling the passage in that member, an annular lip formed on said element and opposing said sealing surface around the entire circumference thereof, said lip being inclined radially inwardly and axially toward said annular sealing surface to engage and to flex and at least partially flatten against the surface around the entire circumference thereof when said sleeve and said skirt are telescoped, said pressure fluid urging said lip against said sealing surface, and means for releasably connecting said members with said sleeve and said skirt telescoped.
