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. The spring elements then return to their initial configuration thereby engaging the retaining flange, preventing relative axial movement between the plug and the receptacle. The coupling is readily detached by rotating the collar thereby forcing the locking assembly into the disengaged position, and extracting the plug member. The coupling also includes a sealing member which renders the connection fluid-tight.
