<p>PROBLEM TO BE SOLVED: To connect a strap body and a yarn ring string without caulking, and to couple the ring string to a connection member without passing a loop-shaped bulging end of the ring string through a narrow passage in the connection member for the connection. SOLUTION: A cylindrical female body 1 which has hooking step edges 1A in the upside and downside and two male bodies 2 which are coupled to the female body 1 by being inserted from the upside and downside, are employed for the connection. At the bottom section 2A of a first male body 2, a string passage hole 4 is formed which has a size through which the flexible thin strong yarn ring strings 3 can be inserted but a lump 3A such as a knot formed on the strings 3 can not. The first male body 2 is formed on the peripheral surface with a longitudinal peripheral surface dividing slit 5 which communicates with the string passage hole 4, with another longitudinal peripheral surface dividing slit 5A which does not communicates with the hole 4 and is disposed on the opposite side of the former slit, and with a circumferential projection 6. By pressing the firs male body 2 provided with the ring string 3 and a second male body 2 provided with the strap body into the female body 1 from the downside and upside respectively while overcoming a characteristic resilience of the male bodies, the circumferential projection 6 of each male body and the hooking step edges 1A in the upside and downside of the female body are engaged to couple the two male bodies 2 on to one female body.</p> |
