The connection of a plastic pipe to another plastic part, wherein a ) the outer layer of the plastic pipe and the outer layer of the other plastic part are largely opaque to laser light of a certain wavelength; b) both the plastic pipe and the other plastic part are sheathed at the ends by an additional adaptor made of a plastic transmissive to laser light, c) and the adaptor is fastened by means of laser-beam welding, produces connecting points which have improved pulling-out resistance and torsional security even at relatively high temperatures. Corresponding composite parts are used in particular as motor-vehicle pipelines. |
