The invention relates to a T-piece (11) and an angle piece (12, 13) as fittings (1) for producing a pipe union. The weak points on the center part (20) of the fittings (1) have an external ribbing (5) for reinforcement against the pressure load enacted in operation. The invention further substantially relates to the design of the ribbing (5). The fitting (1) is preferably designed as a one-layer plastic injection molded part. The invention further relates to the design of an external thread (63) on the fitting (1) by means of thread rings (6) to be arranged on the connecting piece thereof (21-23) and a retaining ring (7) integrated in the pipe union to prevent independent loosening of the screw connection. |
