Abstract: An exhaust gas heating element comprises a wafer that is substantially cylindrical with an axis and is made of metallic foam. A flexible, electrical insulating sheet covers an edge of the wafer with an overlap on each face of the wafer. A rigid assembly ring, a housing, and two electrodes are also provided. The rigid assembly ring is made from a cylinder trunk, at least a first edge of which is serrated in such a way as to be able to immobilize the wafer and the flexible, electrical insulating sheet in the rigid assembly ring by folding teeth, substantially at 90°.
