The invention relates to a fork-type loose leaf binder made in one single integrally formed detail. The fork pins (13, 14) are made directly in the spine parts (11, 12). The spine parts, the cover panels (15, 16) and the latch (17) can be turned in relation to each other by integrally formed hinge sections (18, 19, 20, 21). The binder is also specially prepared for rational piling in compact delivery packages. |
