A duct for protecting a submarine cable is provided to prevent the damage caused by fishing implements and an anchor which falls under the sea by manufacturing a unit body in an arch shape. A duct for protecting a submarine cable includes a plurality of unit bodies(100). The unit body has a cover unit(110) which has a predetermined length along one way and has an arch-shaped cross section along the width, a fixing unit(120) which is extended from both front sides of the cover unit, and a first projecting unit(140) which has a smaller diameter than the middle at both ends of the lengthwise direction, and a second projecting unit(150) which has the larger diameter than the middle. The first projecting unit and the second projecting unit are formed in the shape to contact with each other. A coupling groove is formed at the inner surface of the second projecting unit, and is closely coupled with the outer surface of the first projecting unit. |
