Common reference numerals are given and detailed explanation thereof is omitted. The metal connector 8 is generally made by joining both ends of a hand strap 2 made of a flat string by abutting or overlapping them, and then overlapping this joined part on the back side of the middle part of the ring-shaped string, and then attaching the joined part to the back of the middle part of the string. A rectangular metal plate constituting the metal connector 8 is bent into an annular shape and attached to the entire outer periphery, and both ends of the string 2 are connected by this or by claws at both ends of the metal plate. . The hand strap 2, which is formed into an annular shape with both ends joined in this way, has a handle consisting of the large diameter annular portion 2b and a hanging portion consisting of the small diameter annular portion 2a, centered around the attachment portion of the coupling device 8. The metal hanging ring 3 is divided into two parts and is engaged with this hanging part.

However, since the metal connector 8 is made of metal, the connection structure using the conventional coupling device described above is prone to damage to the string due to handling at the contact point between the end of the metal ring and the string, resulting in rust, discoloration, etc. Problems are unavoidable, and there are also problems such as it getting caught on clothing, etc. In order to solve these problems, conventionally, for high-end products, the entire outer periphery of the metal connector 8 has been covered with heat-shrinkable vinyl chloride, etc., but this is cumbersome and expensive to manufacture. There is a problem. On the other hand, the conventional resin coupling device 10 is manufactured by individually molding using a large molding machine, and it is difficult to automate the manufacturing process, and mass production effects cannot be expected. Furthermore, there are technical difficulties in that the string is easily deformed due to heating and pressure of the material during molding, and burrs are likely to occur at the joint between the string and the end of the connector.
