A pipe coupling device comprises a hollow body member (1) having at least one terminal portion (2) for receiving an end portion of a pipe to be coupled to the device, an 0-ring seal (5) housed within the terminal portion (2) for sealingly engaging the external surface of the pipe, a grab washer (14) having a number of tube-gripping teeth (15) which normally prevent withdrawal of the pipe and axially movable release sleeve (16) for releasing the grip of the teeth (15) on the pipe when it is desired to withdraw the pipe from the device. The grab washer (14) and the release sleeve (16) are located by means of an annular cap member (10) that engages, as a snap fit, the external surface of the terminal portion (2). <IMAGE> |
