Abstract: The invention relates to a device for holding sheets provided with perforations, preferably endless perforations, in a folder. The holding device comprises a base body portion (6) and a holding loop member (7) with two limbs (12,16). One limb (12) can be rotationally fitted into the base body portion (6) through the perforations in the sheets which are disposed one upon the other, whereas the other limb (16) can be resiliently retained in the base body portion (6) by turning the loop member (7).
