<p>PURPOSE:To prevent dust and concrete from being infiltrated from a void by blocking the void on the periphery of the engaging click of a socket, with a blocking member having flexibility. CONSTITUTION:In the sockets 11 of a coupling 10, the engaging clicks 12 of the tips projected inside the sockets 11 are arranged as wire pipes are engaged. The engaging clicks 12 are deflected at the time of inserting the wire pipes, and so on a drum wall along the peripheries of the engaging clicks 12, U-type notches 13 are formed. On the engaging clicks 12, a soft resin sheet 14 as blocking material for covering voids due to the notches 13 is bonded. The soft resin sheet 14 is formed with an elastic member, and so the deflecting property of the engaging clicks 12 is not prevented from being generated, and the voids can be blocked.</p> |
