The pairs of clip arms (b1,b2) are made of flexible material and are shaped in diameter so that they can be inserted through the perforations in the closure flaps of dispatch bags or ring binder inserts for closing or filing them. The head of the clip (a) with diameter (2) is shaped so that only the part (1) with diameter (1) can be inserted through the holes in the ring binder inserts or the flaps of the dispatch bags.
