To provide a wire rod coupling metal capable of easily and surely coupling receiving tools to each other at their 'erecting parts' and shortening the working time required for the coupling.

This wire rod coupling metal 100 for receiving tools couples the receiving tools composed of multiple metal wire rods with each other by coupling the multiple metal wire rods constituting the receiving tools. This coupling metal is provided with a wire rod storage part 10 storing the multiple metal wire rods, a pull-out prevention means 20 formed with the wire rod storage part 10 and preventing the multiple metal wire rods stored in the wire rod storage part 10 from being pulled out from the wire rod storage part 10, a height adjusting means 30 formed in a lower end of the wire rod storage part 10 and pushing upward the wire rod coupling metal 100 itself so as to push the upper part of the wire rod coupling metal 100 toward the lower surfaces of the other metal wire rods, and a detent means 40 disposed opposite to the wire rod storage part 10 and abutting on the other metal wire rods disposed orthogonally to the metal wire rods. This coupling metal is characterized in coupling the receiving tools at the erecting parts.
