Cable protection and guide devices are susceptible to the generation of wear powders from friction between the cable and front and rear end portions of the connecting plates. The generation of wear powders and damage or disconnection of the cable is prevented and abrasion loss and impact noise due to contact between the side plate units is suppressed. Connecting plates 120 are symmetric such that the inner surface thereof includes small curvature portions, large curvature portions, and a flat surface or approximately flat surface having a radius of curvature which is larger than the large curvature portions.
