することかできる。First, FIGS. 1 and 2 show embodiments of the present invention,
In this embodiment, a pair of substantially rectangular parallelepiped-shaped engagement protrusions (7) or two peaks (4) are provided at the valleys (5) of the externally corrugated tube (3).
A pair of notches (8) into which locking protrusions (7) are inserted are formed in the tube insertion holes (2) of the box (1). Therefore, in this embodiment, after cutting the externally corrugated pipe (3) in front of the locking protrusion (7), the cut end is engaged, and the protrusion (7) corresponds to the notch (8). When the tube is inserted into the tube insertion hole (2) of the box (1) in this state and rotated approximately 90 degrees, the locking protrusion (7) will fit into the peripheral wall of the tube insertion hole (2) of the box (1). Then, the outer surface corrugated tube (3) can be fixed to the box (1).
