Abstract: The invention relates to a pipeline fitting and method of using the same. The fitting includes at least one but typically a number of gripping means (16) which include gripping members (1) which can be selectively moved to contact the pipeline (10) wall and exert a gripping force on the same. Movement between the gripping member (1) and guide means (2) within a predetermined range and manner allows relative movement between the pipeline and the fitting, especially after installation, to be taken into account and still ensure that the integrity of the fitting with the pipeline is maintained by maintaining the gripping effect of the gripping means (16) on the pipeline.

Abstract: A pipe fitting for the location of at least one pipeline therewith, said fitting includes a body (5) which supports an annular portion (2) which is movable with respect to the body (5) at the time of installation by operating actuating means (3). A further annular portion (4) is provided to form a fluid tight seal with the pipeline portion. The pipe fitting also includes a number of gripping members (1) at spaced intervals around an annular path and which are located in position in respective recesses formed in the further annular portion (4) and which are movable to an initial gripping position at the time of installation and are then movable to exert and maintain a gripping force on the pipeline once the pipe fitting has been installed.
