The present invention relates to a fixture to be mounted in a mounting hole in a ceiling or the like and an attachment device of said fixture, wherein said fixture is provided with an electrical connection means and a mechanical stopping means, the electrical connection means including a power supply port that can be connected by a simple operation, and the mechanical stopping means capable of removably fixing a heavy and elongated fixture in the mounting hole, so that, when the fixture is mounted in the mounting hole, both electrical and mechanical connection is simultaneously done. By an integrated design of the fixture wherein the back of the mounting hole (a space behind the ceiling panel or the like) is used as a housing space for a lighting circuit member, etc., the fixture can be made more compact with an improved design flexibility, and changes and movements of fixtures with respect to the mounting hole become possible.
