PURPOSE:To improve operability by providing plural clamping pieces which are formed of a rubber elastic body in a projection shape and have their lower wide parts arranged in contact in an abacus-bead state, and clamping optical cords in U-shaped grooves each formed of two projection parts of adjacent clamping pieces. CONSTITUTION:The plural clamping pieces 4 are formed of the rubber elastic body in the projection shape and has two recessed parts 4a at both upper end parts, and lower side parts 4b are fitted and supported in contact with a rod 3. Therefore, U-shaped grooves 5 are formed of two recessed parts 4a to length L at upper parts of two adjacent clamping pieces 4. An optical cord 7 whose one end part is connected to an optical connector 6 is fitted in a U-shaped groove 5 and then the optical cord 5 is clamped on both end surfaces of the groove 5 while receiving lateral pressure, so that both end surfaces of the groove 5 and the optical cord 7 contact each other uniformly to overall length L. Consequently, optical cords 7 are arrayed and held with stable force and the operability is improved.
