出することが防止される。According to the present invention, there is provided a curved portion protective cover, wherein an engaging portion for engaging with a locking portion of another protective cover is provided on an outer surface of a connecting portion constituting the protective cover. The part is restricted from moving in the longitudinal direction (connection direction),
Similarly, the inner surface is provided with a contact portion that is in contact with the outer surface of the pipe member housed in the protective cover, so that the connection portion is restricted from moving in the radial direction of the pipe member. For this reason, even if the piping material is bent and the bellows portion is deformed, the movement of the connection portion in the longitudinal direction (connection direction) is restricted. In addition, even if the bellows portion is deformed to the connecting portion and the connecting portion attempts to deform in the radial direction of the pipe material, the connecting portion hardly deforms because the contact portion is in contact with the outer surface of the pipe material. The engagement between the locking portion and the engaging portion is not released. As a result of the above, during construction,
Alternatively, even if some external force acts on the curved portion protective cover after construction, the connection portion does not come off from the connection port of another protective cover, and the piping material in the curved piping portion is prevented from being exposed. .

It is possible. Further, when a lid fitting portion to which a lid of another protective cover is fitted is provided outside the connecting portion, the movement of the connecting portion is regulated by the lid, so that the connecting portion is bent. The connection portion of the unit protection cover is more difficult to come off.
