Abstract

An exhaust gas treatment assembly for an exhaust gas system of an internal combustion engine includes a housing defining a longitudinal axis. A first exhaust gas treatment unit is inserted in the housing and has a first casing and at least one first exhaust gas treatment unit carried in the first casing. A second exhaust gas treatment unit is inserted in the housing and has a second casing and at least one second exhaust gas treatment unit carried therein. A locking arrangement is for locking a first exhaust gas treatment unit in the housing at least against movement in the direction of the longitudinal axis in a locked state, wherein, when the first exhaust gas treatment unit and the second exhaust gas treatment unit are inserted in the housing, the locking arrangement is blocked in the locked state by the second exhaust gas treatment unit.
