The coupling member comprises a pair of opposed guide studs, a pair of opposed resilient engaging studs mounted in a circles on one end of the hook body and a bridge block also mounted on said one end of the hook body, disposed between the engaging studs with spaces left therebetween and interconnected with the guide studs, each opposed engaging stud having an outward-projecting prong formed on the upper end, the guide studs being round in their respective outer peripheral surfaces and having the outer round peripheral surfaces run along an imaginary circle which is slightly less in diameter than the pivotal hole, the outward-projecting prongs of the engaging studs being forced through the pivotal hole against the resiliency of the engaging studs and snapped into engagement with the pivotal hole under the resiliency so that the hook member is pivotally mounted on the web-engaging member.
