ABSTRACT:
A connector fitting in the form of a sleeve for use on synthetic resin pipes has heating wire let into its inner face for heating the sleeve material and the ends of the pipes to be joined so that a fusion weld is produced. In order to have the wire so fixed in place that on the one hand there is no danger is its being pushed out of place when the pipes are slipped into the fitting, while on the other hand taking care of inaccuracies in the size of the pipes, the wire is let into a cut or groove, that has been opened up, in the fitting and the edges of the cut are overlapped onto the wire so that it is well locked in place.
