Abstract

An exhaust gas muffler for an internal combustion engine, especially in a manually guided implement such as a power chain saw and the like, is provided. The muffler has a housing having an inlet opening and an outlet for engine exhaust gas. An essentially cylindrical spark killer screen is fixed in position at a wall opening of the muffler housing that forms the outlet. The spark killer screen projects into the interior of the muffler housing. Adjoining the spark killer screen on the outer side of the muffler housing as an extension of the cylindrical spark killer screen is an exhaust gas pipe. This pipe is provided with threads and serves as a fastening device with which the spark killer screen and the exhaust gas pipe, as a fire protector, are fixed in position in the wall opening of the muffler housing.
