The pellet has a pellet body (14) to be inserted axially in a complementary female receptacle housing (16) that is equipped with electrical connection terminals (18, 26). A push button (34) causes closing of an electrical circuit that supplies electrical current to a filament resistor (32). The filament resistor has a lighting side (42) that is parallel to an insertion axis of the pellet. An independent claim is also included for a motor vehicle comprising a heating pellet of an electrical cigarette lighter.
