1. Pipe connecting element, particularly angle piece or bifurcating piece, to connect pipes (18, 21) which consist essentially of a continuous inner pipe (23, 44) and projections (25, 45) connected with it which extend radially outwards and serve for the stiffening of the pipe, particularly for the connection of double walled pipes or corrugated pipes, characterized in that the pipe connecting element consists of connected with each other sections (1 to 9), which are formed by a core pipe (16, 16') with outwardly extending radial projections (25, 45) and a jacket pipe (17, 17'), in that adjacent sections (1 to 9) are connected on their butt joint surfaces (10 to 15, 15') in such a manner that the core pipes (16, 16') and the jacket pipes (17, 17') each of these adjacent sections (1 to 9) are connected with each other, and in that the core pipe (16, 16') and the jacket pipe (17, 17') of each section (1 to 9) are firmly connected with each other. |
