[Prior Art]

 Conventionally, as one of the connectors used for connecting such objects, there is one shown in FIG. 3, which has the same structure as the carabiner of the climbing tool. This type of connector has a problem that the spring on the C-shaped annular link 1 for urging the stopper S for preventing the fastening rope from coming off tends to close the opening 0 and rusts and easily breaks. Further, since it is heavy, the centrifugal force due to the rotation of the tire becomes unbalanced when the ends of the fastening members of the anti-slip device mounted on the automobile tire are connected, which is not preferable. Furthermore, the number of manufacturing processes is large and the cost is high.

As another conventional connecting tool, there is one shown in FIG. The conventional product shown in FIG. 4 has a structure in which a metal-made substantially C-shaped link 1'is fixed to a rubber protrusion P whose tip is inserted into the area of the opening 0'of the link l '. . In this conventional product, the rubber protrusion P constitutes a part of the ring connecting the ends of the fastening rope, so that the fastening rope is not always prevented from coming off.

In addition, in the conventional product of FIG. 4, when the fastening rope is short, if two ends of the fastening rope are connected by connecting two connecting tools so as to correspond to the shortage, the two ropes will be vibrated as the tire rotates. The contact portion of the tool, that is, the metal link 1 ', is rubbed to form a rough surface such as a file or a smooth skin. If the ends of the fastening ropes of sufficient length are connected using this worn-out metal link, the joints of the fastening ropes will be damaged and broken at the rough surface like a file or a rough skin. There is a danger of coming.
