ABSTRACT:
A pipe coupling (1) comprising a tubular body (2) having at least one open end (3,4,5), a stop component (14) disposed within the tubular body distal to the open end to stop a pipe when it is inserted a predetermined distance into the tubular body. A sealing component (15) is intermediate the stop and the open end and a pipe engaging component (17) is disposed intermediate the sealing component and the open end having a variable diameter to clamp and release an inserted pipe as a result of the diameter of the pipe engaging component reducing and increasing respectively. A pipe release component (21) is disposed intermediate the pipe engaging component and the open end, the pipe release component being movably mounted on the open end and having a pipe clamping position.
