Zusammenfassung:The invention concerns a post-treatment device comprising an enclosure (12) defining a tubular chamber inside which a deflector element is disposed, comprising: -at least one substantially ring-shaped support means extending parallel to the wall of the enclosure with a predefined clearance (J1), supporting the deflector elements substantially at the centre of the tubular chamber by means of at least two arms, the ends of which are attached to the support means and to the deflector element, -two holding elements (28, 30) positioned to either side of said support means (24) axially, between same and the enclosure (12), each having an open, substantially annular general shape with radial undulations, in contact alternately with an inner surface (12a) of the enclosure and a bearing surface (24a, 24b) facing the support means (24), said radial undulations being shaped to radially block the support means relative to the enclosure.
