Abstract: A linear object identification tag is a linear object identification tag 10 which can be attached to and detached from a linear object 40. This tag has a clip body having a pair of clip parts 1a, 1b openably joined to a base part 6, and a holding part 8, 9 which holds the linear object 40 inside the linear object identification tag and is formed on an inner face of at least one of the clip parts 1a, 1b. Therefore, installation is possible by simply inserting the linear object 40 from an aperture part 7, and the efficiency of the installation operation can be greatly improved.
