Abstract
The invention relates to a flange coupling of two pipes, in particular the pipes of an exhaust system of a motor vehicle internal combustion engine. The coupling is characterized in that: each of the flanges is formed onto the corresponding pipe by the shaping of one of the pipe regions that form the respective flanges; a first of the two flanges is configured with a first connection pipe section, which engages radially in the interior of the second flange; a sealing ring is clamped between the flanges; the flanges are axially fixed by a clamping deice. The coupling is designed to be produced in an efficient manner, easy to mount and configured so that it functions reliably.
