A coupling nut (4) connects the collar part and the plug-in part with each other. A set of seals (6, 7) is provided between the collar part and the plug-in part, and/or between the plug-in part and the coupling nut. An additional sealing ring (8) is arranged at a front side between the collar part and the plug-in part and fills a pipe line-side gap between the collar part and the plug-in part. The sealing ring is made of glass-fiber reinforced plastic. The sealing rings are made of fluroic rubber and/or fluoro carbon rubber.
