Abstract: A heating element for a vehicle exhaust gas purification device is provided and is to be disposed in an exhaust gas duct. The heating element extends around a central axis. and comprises a central support defined around the central axis, a heating grid extending radially around the central support, and a liaison element. The liaison element comprises a plurality of mounting brackets comprising at least a first part connecting the mounting brackets to the heating grid, at least a second part connecting the bracket to the duct, intended to be directly or indirectly attached to the duct, and at least one intermediate section connecting the first connecting part to the second connecting part. The connecting element is at least partially radially flexible.
