A cable holder is deposited and fixed on an inner wall of a sewage pipe made of resin and supports an optical fiber for communication, which is passed through the pipe. The cable holder has a longitudinal section similar to that of an inverted pot and a narrowed inlet opening, and is provided with a pair of claws arranged in the axial direction of a pipe at its upper part. A cable holder driving device is raised in a state where the cable holder is heated and a pair of claws are pressure-fitted into the inner wall of the pipe. The pressure-fitting is carried out to such a degree that the cable fitted to and supported by the cable holder is brought into contact with the inner wall of the pipe. After the cable holder is cooled down and fixed, the cable passed through the pipe is pushed in the cable holder through its inlet opening.
A method for attaching a cable to an inner wall of a resinous pipe, comprising the steps of:
A resinous pipe and cable holder combination comprising a longitudinally extending resinous pipe and a metallic cable holder comprising an attaching portion and a cable holder portion, said attaching portion comprising claws embedded in an inner wall of the resinous pipe and arranged at a fixed interval in the axial direction of the pipe and said cable holder portion having a narrowed inlet opening provided opposite to the claws, an expanded body portion and a longitudinal cross-section similar to that of an inverted pot.
