And the connection work can be performed smoothly, and this is a first object. Further, according to the present invention, as one of the first objects of the present invention, the connecting member is formed of a metal plate, and one or both of the connecting hook and the hook mounting hole are reduced due to direct contact between the hook and the hook mounting hole. It is a second object of the present invention to prevent various harmful effects such as a metallic sound.

[0006]

In order to achieve the above-mentioned object, the technical means of the present invention is provided at both ends of an inner tightening rope attached to an inner side edge of a non-slip body through a connecting hook. In the connecting member composed of the inserted body and the receiving body provided, the inserting body and the receiving body are each formed of a thin flat metal plate, and the inserting body is formed into a thin flat shape. An engaging hole is formed near the front end of the formed insertion piece, a rope connecting part is provided on the rear end side, and a hook attachment part is protrudingly provided on one side near the rear end of the insertion piece. The receiving body is provided with a rope connecting part at the rear end, and a box-shaped inserting body insertion part with a hook attachment part protruding on one side near the rear end, and is installed inside the insertion part against the elastic force. And an elastic piece formed on the surface thereof so as to fit with the engaging hole of the insertion piece. An operation piece having a claw protruded therefrom and a spring piece. The operation piece has a tip locked to a tip locking portion provided below the insertion port of the insertion body insertion portion, and a spring piece is attached to the insertion portion. The bottom surface is cut and raised at a desired position, locked to a protruding spring piece locking portion, arranged upwardly from the front end side, and constantly urges the engagement claw toward the upper surface of the insertion portion, and at the rear end, The pressing operation piece is made to protrude to the outside, and each of the hook attachment portions has a resin eyelet attached to its attachment hole.

[0007]
