Pipeline connection and method of manufacturing pipeline connections made of polyolefine.

The invention relates to a method for forming a sealed clamp between a terminating end of a clamping clamp tube and a connecting part, in which process the connecting element is provided with a protrusion projecting with the end of the pipe end, b) expanding at an inner diameter of the pipe end at an inner diameter of less than the outer diameter of the connecting part, an inner diameter larger than the outer diameter of the connecting part, the expanded end of the pipe is subjected to the surface pattern of the coupling surface, and at the ambient temperature, with a reverberant refining of the coupling part, the retractors are retracted. The main object of the present invention is to heat up a plastic tightening ring (5) having an internal diameter of at least equal to the outer diameter of the end end (4), and (e) the bushing (4) together with the tensioning ring (5) before extending the pipe end (4) (1) extending over the outer diameter of the connecting part (1), and (f) extending an extension portion (1) on the surface pattern of the coupling part (1) and extending along the tensioning ring (1) on the surface pattern of the coupling part (1). ŕ
