Abstract: A heating device comprises a heating element having a central area and a peripheral edge. The heating element has a series of slots delimiting a series of longitudinal branches connected to one another by elbows. The central area is made of a first electrically conductive material that is permeable to exhaust gases and has a first relative density. The elbows are located in the peripheral edge and are made of a second electrically conductive material and that has a second relative density greater than the first relative density.

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°.

Abstract: An exhaust gas heating device includes a housing and a heating element arranged in the housing for heating exhaust gases flowing through the housing. The heating element comprises a first and a second connecting region. A power source for supplying electricity to the heating element, comprises a first connecting element, connected to the first connecting region of the heating element, and intended to supply the heating element (18) with electricity, and a second connecting element. The electrical power source comprises a third connecting element that comprises an electrical connector, electrically connecting the second connecting element to the second connecting region of the heating element.
