PROBLEM TO BE SOLVED: To provide mounting reinforcing twin union wires for preventing falling of an illumination fittings in tunnels or the like or a fascia, in which there is no risk for the whole body to be broken even if a covered outer sheath becomes damaged, and which is inexpensive and superior in workability. SOLUTION: This is the mounting reinforcing twin union wires for preventing falling of the illumination fittings in the tunnels or the like or the fascia, wherein at least two metal wires and two chemical fiber cords are included and wherein the metal wires and the chemical fiber cords are arranged so that they are mutually adjacent, and that the two metal wires are mutually opposed and the two chemical fiber cords are mutually opposed, and that their surroundings are covered and sheathed by insulating materials in order that the whole of them is fixed in a mutually twisted state (twisted state).
