A cigarette lighter plug includes a front housing and a rear housing, a positive contact end installed at a front end of the front housing for contacting a positive terminal of a cigarette lighter socket, and an elastic element encircling a connecting portion of the front housing and the rear housing for contacting a negative terminal of the cigarette lighter socket. When the elastic element contacts the negative terminal of the cigarette lighter socket, the elastic element is electrically connected with the negative terminal of the cigarette lighter socket.
