ABSTRACT:
A filtering body (3), in particular for a motor vehicle internal combustion engine exhaust gas particulate filter (1), includes a plurality of filtering units (11a–11i) assembled by at least a joint (12) interposed between the filtering units (11a–11i) and configured so as to counter the passage of exhaust gases between the filtering units (11a–11i). The filtering body is characterized in that the joint (12) comprises a plurality of joint portions (12a–12e) locally adapted to optimize the attenuation of thermomechanical stresses liable to be generated in the filtering body (3).
