Patent ID: 8763375

Claim:
An exhaust gas cleaning device of an exhaust system of a combustion engine, comprising: a catalytic converter unit having a catalytic converter support pipe defining an interior peripheral surface and at least one oxidation catalytic converter element mounted in the catalytic converter support pipe, a particle filter unit having a particle filter support pipe defining an interior peripheral surface, and at least one particle filter element mounted in the particle filter support pipe, a receiving pipe in which the catalytic converter support pipe is axially inserted, a clamp connection which sets the receiving pipe, the catalytic converter support pipe and the particle filter support pipe against one another; wherein the interior peripheral surface of each of the catalytic converter support pipe and the particle filter support pipe are at least partially in axial contact with one another; wherein the receiving pipe at a face end in the clamp connection comprises a circumferential receiving pipe collar standing away to the outside, the catalytic converter support pipe at a face end in the clamp connection comprises a circumferential catalytic converter support pipe collar standing away to the outside, and the particle filter support pipe at a face end in the clamp connection comprises a circumferential particle filter support pipe collar standing away to the outside; wherein the clamp connection comprises two clamping rings and a clamp axially clamping the two clamping rings towards each other; wherein one clamping ring is designed as a receiving pipe clamping ring, which axially abuts the receiving pipe collar on a side facing away from the catalytic converter support pipe collar, while the other clamping ring is designed as a support pipe clamping ring which axially abuts the particle filter support pipe collar on a side facing away from the catalytic converter support pipe collar.
