Beschreibung
Zusammenfassung:	To form a junction for a pipe (2) on a nozzle (1), with at least one ring structure (4) with the shape of a fir tree, the pipe is fitted on the nozzle to leave a free space between the inner surface of the pipe and the outer surface of the nozzle in the vicinity of at least one of the ring structure flanks in a multi-ring configuration to give secondary fir tree and olive rings (5,6). The nozzle is inserted into the cavity of a mold, and the pipe is distorted by a mold support. A plastics material is injected into the mold cavity, to pass between the mold support and on the ring structure to form a molded collar (3). The support force within the mold ensures that the pipe is sealed at the nozzle.
