An electric glow element has a heating-conductor coiled band inside of a glow-coil dish, with a mechanically strong clamped connection between the coiled band and the glow-coil dish. The connection has good electrical conductivity, and is formed by a first bead in the glow-coil dish base wall and a side wall of the glow-coil dish which is concavely curved towards the inside of the dish. A second bead is formed outside of the first bead, and serves to clamp a band end of the heating-conductor coiled band firmly, fixing the heating-conductor coiled band end between the base wall and the side wall. In a second embodiment, a single bead connects the base wall and the curved side wall. The single bead extends below the plane of the base wall, and receives the second band end. The second band end extends out of the coil plane of the coil, and the glow coil is disposed in the interior of the glow coil dish and is oriented so as to have its coil plane generally parallel to the base wall.
