In order to connect a connection piece (10), which is, for example, a pipe coupling or a mounting or a fitting, to a thermally insulated conduit pipe (1), a clamping sleeve (9) with an internal thread (8) is screwed in between the internal pipe (2) of the conduit pipe and the insulation layer (3) of the conduit pipe. A connection body (11) with a plug sleeve (13) is arranged in the internal pipe beforehand. The clamping sleeve (9) acts indirectly on the connection piece (10) by way of a retaining ring (14) in order to press the connection piece against the end face (5) of the internal pipe (2). In this way, the distance between the insulation layer (3) and the casing (4) of the conduit pipe is dispensed with and inaccuracies when cutting the conduit pipe to length can be compensated. |
