Abstract: A connector including a male member and a female member adapted to mate therewith. The female member is hollow and has an annulus defining a plane substantially perpendicular to its axis. There is a substantially cylindrical hollow nozzle within the annulus and the nozzle has an outer diameter smaller than the inner diameter of the annulus, thus defining a space therebetween. A hollow portion extends away from the male member and is being substantially coaxial with the nozzle. The male member is generally cylindrical and hollow. It is provided with a collar having an outer diameter smaller than the inner diameter of the annulus and an inner diameter larger than the outer diameter of the nozzle, whereby the collar occupies the space. The male and female members, when connected, form a passage for flow of fluids therethrough.

Abstract: A connector having a male part and a female part, the latter having a hollow body and a hollow housing portion connected thereto to form a passage for flow of fluid. The portion is provided with at least one detent on the inside wall and has an opening on the end remote from the body. The detent is provided with a sloping surface which flares in the direction of the opening and also has an abutment surface facing toward the body.The male part has a front end which is inserted into the opening and carries an inclined surface which is complementary to the sloping surface of the female part. In a manner analogous to the female part, the male part is provided with an abutment facing away from the front end and adapted to abut the abutment surface on the female part when the connector is in closed position.
