Abstract
A heating plug for an electric cigar lighter, in particular for a cigar lighter equipping a motor vehicle, has a plug body designed to be inserted axially in a complementary female socket body equipped with electrical connection terminals. A push button is mounted so as to be able to move axially with respect to the plug body, between a neutral position and a pushed-in position in which it causes closure of an electrical circuit for supplying electrical current to a heating element arranged in the plug. The heating element has a lighting face which is accessible from the outside of the plug when the plug is removed from the socket body. The lighting face of the element is roughly parallel to the insertion axis of the plug.
