The locking shoulder 27 engages with the edge of the mounting hole 30 by returning from the side surface so as to project outward. As a result, the first panel 5 is connected to the second panel 6 in close contact with each other.

  The clip 1 may be pre-attached to the first panel 5 at a location where the second panel 6 is present, but can also be performed at a location away from the second panel 6. For example, when the second panel 6 is an elevator wall panel, the first panel 5 to be attached to the wall panel is preliminarily clipped with a clip 1 at a factory or the like, and the clip is installed at the site where the elevator is installed. The first panel 5 with 1 may be delivered. Accordingly, it is not necessary to deliver the clip 1 alone, and the labor for attaching the clip 1 to the first panel 5 at the work site can be saved. In addition, the clip 1 can maintain the connection intensity | strength to the 2nd panel 6 high by attaching to the several predetermined location of the 1st panel 5 beforehand.

  In the above description, there are two panels to be connected, but even three or more panels can be connected. Also, if the panel to be connected is the side wall plate of the elevator, the work space is small outside the car room, but the clip can be attached to one of the panels, so that the panel can be connected without any trouble. Since the operation is simply pressing and engaging the other panel with the other panel, no tool is required and the operation time can be greatly shortened.
