MO-8-24401M/YO/80 ABSTRACT OF THE DISCLOSURE A wiring guide for telephone or electric lines in which the lines can easily be inserted through the pipe through length of more than 100 meters. The wiring guide is formed as a fiber-reinforced plastic bar having a flexural rigidity of at least 2 x 106 kg mm2 and a weight per unit length of no more than 100 g/m. Long reinforcing fibers are arranged at an angle of ?45° with respect to the longitudinal direction of the fiber- reinforced plastic bar. For the reinforcing fibers, carbon fibers can be used alone or carbon fibers along with other organic fibers. The plastic bar may be made electrically con- ductive so that its position can be detected by an electric field generated by passing a current through the bar.
