摘要
A substantially tubular reinforcing sleeve is disclosed and is designed for placing inside a coupling pipe in an assembly with the coupling pipe which forms part of a coupling. The sleeve is provided with a slit extending at least in axial direction of the reinforcing sleeve, and the slit is enclosed by slit edges of the reinforcing sleeve. The slit edges define an intermediate space which is variable in that the sleeve takes a flexible and resilient form. The dimensions and the form of the reinforcing sleeve are chosen such that the contour of the reinforcing sleeve can be placed inside a coupling pipe and there connects closely to an inner wall of the coupling pipe after placing. The reinforcing sleeve optionally includes toothings for fixation to the coupling pipe. A method is further disclosed for welding an outer end of a multilayer conduit to the above stated assembly.
