To facilitate an attachment operation to a marine cable or the like in a protective pipe.SOLUTION: A protective pipe 1 is formed by disposing a concave surface 31a side of a pair of halved tube bodies 3 opposite to each other. The halved tube body 3 has a connection part 7 which extends outside of a bonding surface 34 with the opposed halved tube body 3 and mounts bolts 4, nuts 5 and washers 6. The connection part 7 has an insertion hole 71 for inserting a screw part 42 and a washer recess 72 into which the washer 6 is fitted. The aperture of the insertion hole 71 is larger than the external diameter of a head 41 of the bolt 4 and is smaller than the external diameter of the washer 6. One of the washers 6 has a ring opening part 62 larger than the shaft diameter of the screw part 42.SELECTED DRAWING: Figure 1
【課題】保護管において、海底ケーブル等への取付作業を容易にする。【解決手段】保護管１は、対を成す半割管体３の凹面３１ａ側を互いに対向配置させて成る。半割管体３は、対向する半割管体３との接合面３４の外側に延設されボルト４、ナット５及び座金６が装着される連結部７を有する。連結部７は、ネジ部４２を挿通させるための挿通穴７１と、座金６が嵌まり込む座金凹部７２と、有する。挿通穴７１の口径は、ボルト４の頭部４１の外径よりも大きく、座金６の外径よりも小さい。そして、座金６の一方は、ネジ部４２の軸径よりも大きな開環部６２を有する。【選択図】図１
