The middle part is made of wire, and both boxes are fastened to each other with the connecting body, thereby connecting both pontoons. Therefore, when connecting both pontoons with the connecting body, the side wall and the box body are connected. Since they reinforce each other, the connection strength between the two pontoons is improved. Moreover, this improvement in connection strength is achieved by embedding the box in the side wall.
In other words, this improvement in strength can be achieved with a simple structure because it is obtained by effectively utilizing the side walls.

Furthermore, since the elastic body interposed between the both side walls and fitted around the wire has a single cylindrical shape,
The elastic body prevents the wire from being easily visible from the outside, thereby improving the external appearance of the coupling device.

Furthermore, the outer surfaces of the above-mentioned both side walls were made into vertical flat surfaces, recesses were formed from the outer surfaces toward the inside of the side walls, and the ends of the above-mentioned elastic bodies were fitted into the respective recesses. This has the advantage that the elastic body can be made longer to increase its elastic deformation, and that the pontoons can be brought closer to each other, making it easier to move back and forth between the two pontoons. .

Moreover, the top surface of each side wall and the top surface of each box body are made almost flush with each other, and an opening is formed at the top of each box body, and a cover plate is provided to freely open and close this opening. Since the top surface of the box body is almost flush, traffic on the top surface of the pontoon can be smoothly carried out without being obstructed by the box body. In addition, since an opening is formed in the upper part of the box body, the operator can operate the fastener through the opening from the top surface of the side wall. It has the advantage of being easy to operate.
