Further, the clip made of plastic has a weaker holding force than the clip made of metal, and there is also a problem that the held documents and the like are easily dropped off. Therefore, in order to solve this adverse effect, the clip for the clip binding tool of the present invention is:
It is preferable that the inner surfaces of the holding portions 4a and 4b of the upper and lower holding plates 2a and 2b are brought into close contact with each other.

Also, since the thickness of the holding plates 2a and 2b of a plastic clip tends to be larger than that of a metal clip, the clip is loaded into a clip binding device and is held by a clip expanding spring 20. If there is some misalignment in the vertical direction when opening the opening, the clip expanding spring 20 may not be inserted between the front end guide portions 3a and 3b and may be caught, which may not be able to smoothly sandwich a document or the like. is there. Therefore, in order to eliminate this adverse effect, the clip for the clip binding device of the present invention uses the upper and lower holding plates 2a,
The thickness of the front end guide portions 3a and 3b in 2b
It is preferable that the thickness be smaller than the thicknesses of a and 4b.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, as shown in FIG. 1, the clip of the present invention has a pair of upper and lower holding plates 2 a and 2 b bent forward from upper and lower ends of the rear end back plate 1, respectively.
At the front ends of the upper and lower holding plates 2a and 2b, guide portions 3a and 3b are provided to slightly separate the upper and lower portions from each other so as to facilitate insertion of a document or the like 21 from the front, and immediately behind the guide portions 3a and 3b. Nipping portions 4a, 4b capable of holding the documents 21 from above and below are provided at the positions, and ear portions 5a, 5b, which protrude outwardly at both left and right end portions of the front end guide portions 3a, 3b and the nipping portions 4a, 4b, respectively. 5c, 5d
