1. Pipe junction with an annular seal (5) made of thermoplastic material located between the outer periphery of a pipeline (1) and the co-related bearing surfaces of a branch fitting (3, 4) and which engages in the groove opening of the branch fitting, thus sealing the branch opening (11) of the pipeline (1) against the branch fitting (3, 4) whereby at the base of the branch fitting there is located opposite the free end of the said fitting above the branch opening an integrate-moulded circumferential, annular shoulder (31) serving to support the circumferential edge of a bush (2) characterized in that the bush in the capacity of a locking bush (2) is provided with a shaft (23) which is fitted into the branch opening (11) of the pipeline (1) and by means of a thread (22) penetrates through the wall cross-section of the pipeline (1). |
