ABSTRACT:
The invention relates to joining insulated elongate conduit members, such as thermally insulated pipes. A pipe (1) is provided with thermal insulation (2), in which, at an end of the pipe, there is an annular recess (6) such that an end portion (4) of the pipe is exposed to allow access for connection thereto. To make a connection, a recoverable connecting collar is positioned at least partially within the recess, and allowed to recover into gripping engagement with the exposed portion of the pipe. The invention obviates the necessity of reinsulating the joint region of an insulated pipe.
