Abstract: A coupling for holding two tubes together and including a housing member connected to the end of one of the tubes and a locking collar rotatably mounted in said housing for rotation between a first rotative position in clamping engagement with an end of a second tube inserted into the housing and into fluid communication with the first tube and a second rotative position permitting insertion of the end of the second tube into the housing.

Abstract: A readily attachable and detachable coupling for connecting conduits, having a receptacle assembly with a profiled bore, a first end designed to mate with one end of a first conduit and a second end adapted to receive a mating plug member. The plug member is provided with a first end adapted to mate with the second end of the receptacle, a second end adapted to mate with a second conduit, a constant diameter axial bore and an annular retaining flange. A locking assembly having an engaged position and a disengaged position is mounted to the second end of the receptacle assembly. The locking assembly includes a pair of resilient spring elements operatively associated with a rotatable collar so that rotation of the collar disengages the locking assembly. The locking assembly is designed to return to the engaged position once the rotative force has been removed. When the plug is inserted into the receptacle, the annular flange outwardly displaces the spring elements.

Abstract: A connector for connecting the confronting ends of tubing sections. The connector includes a connector body having an opening therein which extends therethrough along a longitudinal axis of the housing. The housing includes as first end for connection to the confronting end of a first tubing section. A first annular chamber is provided in the housing between the first end and the second end of the housing for receiving a generally annular seal therein which sealingly engages a second tubing section. A generally cylindrical retaining clip is provided in the housing between the seal and the second end of the housing. The clip includes a pair of diametrically opposed portions thereon which are radially deflectable relative to the axis of the housing.

Abstract: A quick connect connector is disclosed. The connector includes a connector housing having a first and a second ends. A first chamber is provided in the housing between the first and the second ends for receiving a sealing member therein. A retaining collar is slidably mounted on the housing between the first and second ends of the housing and includes at least one radially deflectable locking portion thereon. The radially deflectable retaining portion is adapted to engagingly contact a flange portion of a tubing member inserted in the housing to retain the tubing member in a locked position relative to and sealingly engaging the sealing member between the retaining portion and the first end of the housing. The locking portion is received within a groove of the housing to lock the collar to the housing and secure the connection. The tubing connector is resiliently urged out from the housing and against the engaged retaining portion of the housing.
