Abstract
A pipe coupling apparatus comprising a concentric, relatively telescoping tube is adapted to be inserted into a receptacle. A deformable head at the distal end of the tube is deformable to an enlarged, preselected retention configuration wherein the head engages the inner wall of the receptacle to hold the pipe coupling in a locked position. Relative axial shifting of the tube deforms the head from the locking configuration to a collapsed and elongated configuration wherein the head elongates to facilitate insertion or removal of the coupling from the receptacle.
