PROBLEM TO BE SOLVED: To provide a coupling tool for wiring and piping material receiving tools, which can electrically conducts the wiring and piping material receiving tools to each other easily.SOLUTION: A coupling tool 2 comprises a coupling tool body 2a having a first housing part 2b for housing a first metal wire part 1b of one wiring and piping material receiving tool 1 and a second housing part 2c for housing a second metal wire part 1c of the other wiring and piping material receiving tool 1. The coupling tool 2 also has: a first protrusion part 2d which forcibly bites into the first metal wire part 1b so as to reach base material in an insulating surface-treated film in the first metal wire part 1b and has electrical conductivity provided in the first housing part 2b; and a second protrusion part 2e which forcibly bites into the second metal wire part 1c so as to reach base material in an insulating surface-treated film in the second metal wire part 1c and has electrical conductivity provided in the second housing part 2c. The first protrusion part 2d and the second protrusion part 2e are formed on a metal protrusion part forming body 6, and are in an electrically conductive state between both of the protrusion parts. |
