Abstract: A purification device includes a tubular shell having an inner surface and an electric heating member housed in the tubular shell. The heating member comprises a heating element made of an electrically conductive material which is permeable to exhaust gases. The device also includes an attachment of the heating element directly on the inner surface.

Abstract: The disclosure relates to an electrical connector comprising an electrical conductor, an electrical insulator surrounding the electrical conductor, and a housing surrounding the electrical insulator. A ring surrounds the electrical insulator, and is arranged in an extension of the housing, longitudinally at an end of the electrical insulator and longitudinally spaced from the housing by a length at least equal to one times a thickness of the electrical insulator.

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.

Abstract: A heating member for a vehicle exhaust gas purification device comprises an electrically conductive peripheral frame having an inner edge, a central support arranged substantially at a geometric centre of the inner edge, and a perforated heating grid formed of a plurality of elongate heating elements each having first and second ends opposite one another. The first end is linked to the electrically conductive peripheral frame and the second end is linked to the central support. Each elongate heating element occupies a respective angular sector of the perforated heating grid, and is arranged in zigzag manner within that angular sector so as to form a succession of strands connected by nodes and being linked by the nodes to the elongate heating elements occupying neighbouring angular sectors.
