    • PROBLEM TO BE SOLVED: To provide a leading tool applicable both to suspension wires and to self-supporting cables different in outside diameter. SOLUTION: The leading tool for a pull cord for cables is placed inside a spiral cable suspending tool supported on a suspension wire or self-supporting cable strung between poles, connected at its tail end with the pull cord for cables with a pressing wire body composed of a flexible material the length of which corresponds to the distance between the poles, and has on its main body piece long in the fore-and-aft direction a pair of opposite erected anchoring pieces the upper ends of which are anchored to the suspension wire or self-supporting cable placed in the recesses formed in the opposite faces of the anchoring pieces. A supporting portion is formed on the main body piece in the fore-and-aft direction and the base pieces of the pair of the anchoring pieces with a plate spring in-between and locking pieces positioned outside the base pieces are inserted into a support mallet to support it. In addition, a plurality of receiving edges are formed to accommodate coupling portions different in diameter.
