Improved lampholder, characterized in that the dome forms a broad cylindrical skirt with reinforcing end rib and internally has two thicknesses that determine the fixing of the insulating base carrying the contacts by sliding on ramps provided on its periphery, and a tongue on said skirt that ensures the immobility of said base by ratchet effect on serrated portions also provided in the contour thereof; in the neck of the dome a threaded ring with a polygonal flange is attached to one end, which fits in the internal area of the dome adjacent to the neck, and the other end is flaring over which the corresponding end of the neck is refuted, with what is achieved is the immobilization and fixing of the threaded ring in the neck of the dome.
