A connection hole 6 capable of communicating with the protection tube 3 is opened at sidewalls 5 of a box body 4. A retaining part 7 capable of retaining the protection tube 3 from the outside is formed on the outside of the connection hole 6, and the retaining part 7 is provided with an opening part 8 capable of pressedly inserting the protection tube 3 and a locking projection capable of being engaged with the valley parts 2 of the inserted protection tube 3. When the protection tube 3 is pressed into the box from the opening part 8, the retaining part 7 opens outside and receives the protection tube 3, then closes to retain the protection tube from the outside. |
