A pipe coupling (1) comprising a tubular body (2) having at least one open end (3, 4, 5), stop means (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. The sealing means (15) is intermediate the stop means and the open end and a pipe engaging means (17) is disposed intermediate the sealing means 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 means reducing and increasing respectively. A pipe release means (21) is disposed intermediate the pipe engaging means and the open end, the pipe release means being movably mounted on the open end and having a pipe clamping position. |
