To adjust a clip attachment position as necessary, and also to firmly secure a clip attachment state to wire.

Each hook part 11 includes a cut groove 11a obtained by cutting a clip main body 1. The wire W is inserted from the open end 11b of the cut groove 11a into the cut groove 11a, so as to hook the wire W into the clip main body 1. Fitting bodies 2 include first and second holding boards 20, 21, and are fitted by respectively holding the hook parts 11 of the clip main body 1 between the first and second holding boards 20, 21. The second holding board 21 of the fitting bodies 2 is divided into two by a cut groove 21a to allow the wire W to be inserted between the second and first boards 21, 20. While the fitting bodies 2 are fitted to the hook parts 11 of the clip main body 1, at least the open end 11b of the cut groove 11a in the hook part 11 is covered from a side part.
