<p>PROBLEM TO BE SOLVED: To provide a protective tube capable of preventing both separated bodies from mutually widening. SOLUTION: In a protective tube 1, outer parts 1a which are projected to the outside into an annual shape and inner parts 1b projected to the inside in an annular shape are provided alternately. The protective tube 1 includes a first semicircular separated body 1i and a second semicircular separated body 1j joined via hinge parts 1h. At the joining position of these bodies 1i and 1j, a mounting part 1k formed of a first mounting member 1m in the first separated body 1i and a second mounting member 1n in the second separated body 1j is provided. A closing member 2 for covering and supporting these mounting members 1m and 1n is put at the mounting part 1k. In this way, by having the closing member 2 mounted on the mounting member 1k, both the separated bodies 1i and 1j are prevented from mutually widening.</p> |
