PROBLEM TO BE SOLVED: To enable free arrangement by constituting a mounting implement by a socket having an upper face tapered engaging part in both side parts and an insertion port in the intermediate part and a plug which can be inserted from the insertion port to have an extension part in both side parts. SOLUTION: A socket 2 of a mounting implement main unit 1 is formed with an engaging part 4 having a brim part 7 in a lower end part in inner both side parts of a shallow cylinder part, one side of the engaging part has a high upper surface from this side to an opposite side, and the other side in tapered reverse shape is formed with an insertion port 5 between the engaging part 4. A barrel part 11 of the socket 2 is inserted to a circular hole in a reverse surface part of a plate material 13 and screw locked by a machine screw hole 8. A plug 3 has a recessed part inserting a tip end part of a leg 14 in a lower part. An extension part 6 is formed in upper end both sides of a cup part 9. The extension part 6 is inserted from the insertion port 5, the plug 3 is turned, a lower surface part of the extension part 6 is made to abut to an upper surface of the engaging part 4, and the socket 2 is fixed to the plug 3. In this way, mounting the leg in and removing it from the roof or the like can be made by a single operation, and free arrangement can be obtained.
