PROBLEM TO BE SOLVED: To provide a connection restraint jig capable of remarkably suppressing manufacturing cost.SOLUTION: A connection restraint jig (3) comprises a pair of lock pin (31) and a crosslink band (33) cross-linking the pair of lock pins. The pair of lock pins can be inserted through a pair of confronted first engage holes (111) and a pair of confronted second engage holes. The pair of confronted first engage holes (111) are provided in a tubular first connection part (11) located in an end portion of a first stud (1). The pair of confronted second engage holes are provided in a tubular second connection part (21) which is located in an end portion of a second stud (2) connected to the first stud and is externally fitted to the first connection part, and matched to the first engage holes (211). The lock pin is formed by restricting an end portion side of a metallic band-like piece (W) into a convex shape, and the cross-linking band is formed by bending a center side of the band-like piece. Therefore, a connection of studs used for a temporary scaffold or the like of a construction site can be surely restricted while remarkably reducing manufacturing cost. |
