Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
