Abstract

See full text

A muffler, in particular a rear muffler, for an exhaust gas system of an internal combustion engine, in particular a motor vehicle engine, comprises a housing, in particular a housing having a jacket and two end walls, and comprises at least two pipes which are plugged into one another and which are at least partly received by the housing, in particular at least one inlet or outlet pipe which is in particular led through the jacket and which is connected to an inner pipe. The first pipe has a pipe piece into which a pipe piece, in particular an end section, of the second pipe is plugged. The pipe piece of the second pipe is provided with nubs at its outer boundary which engage into cut-outs provided in the pipe piece of the first pipe. In this respect, the cut-outs are dimensioned larger with respect to the nubs so that the end section is, on the one hand, fixed in the pipe piece but can be axially displaced to a limited degree relative to the pipe piece.
