Abstract

Device for the catalytic detoxification of or soot removal from exhaust gases of internal combustion engines, comprising: a housing (4) which has two partial shells (4a, 4b) welded together along longitudinal welded edge pairs (26) and two open end zones (8) connected to an exhaust gas line, as well as a flow passage for the exhaust gas between the end zones. Two exhaust gas treatment bodies (6) are provided through which gas is able to flow. The exhaust gas treatment bodies are arranged one behind the other in the flow direction and are arranged at spaced locations from one another in the housing. A protective ring (14) made of sheet metal is provided which delimits the space between the two exhaust gas treatment bodies (6) on the outside. The protective ring (14) has at least one sheet metal flap (32), which extends between a welded edge pair (26) of the housing partial shells (4a, 4b) and is welded to the housing (4) at the welded edge pair.
