<p>PROBLEM TO BE SOLVED: To solve the problem with a conventional method that it is difficult to determine the positions of things to be connected together so that the attachment/detachment is difficult or the connection is not possible unless force is used, thereby making the connection troublesome or causing the connection to come off easily when the coming-off is not wanted.SOLUTION: Using the elasticity a metal and a plastic possess, the connection of things which are difficult to be connected, and the connection of a chain, a wire, etc. whose connection is troublesome are made to be easily performed by simply pressing a cut portion curved inside a circle against what is to be connected. Furthermore, the invention solves the problem that the connection comes off easily even when the easy coming-off is not wanted.</p> |
