A pipe fitting system comprises a fitting (2, Fig.1) for coupling to a pipe (1, Fig.1) and a tool 16 for releasing the pipe from engagement with a gripping means 6 of the fitting. The gripping means comprises at least two axially extending and generally circumferentially facing opposed bearing surfaces 30 and the tool comprises a member 32 for insertion between the bearing surfaces in such a manner as to urge them apart by acting on them in a generally circumferential direction when the tool is moved towards the gripping means in a direction generally parallel to the longitudinal axis of the pipe. |
