Abstract
A shaped part formed as a welding sleeve, consisting of thermoplastic material with a resistance wire winding arranged on its inner circumference, having at least one weld indicator. The indicator consists of a stem which is formed from the material of the body of the shaped part or sleeve. The stem prevents the material which comes under increased pressure upon the welding operation, and is urged towards the surface of the sleeve, from passing into the free space, by the resting against a corresponding surface of the sleeve recess.
