The clip has a base with two spaced elongate, flexible, serrated members (18) and a retainer (26) with two spaced apertures (32) through which the members pass. Punched paper sheets are threaded onto the elongate members. Adjacent each aperture the retainer (26) has a flexible tab (50) which is flanked by two upstanding undercut formation (36). The tab has locking formations (38) which are engageable with selected serrations (24) on the respective elongate member (18), to secure the retainer to the base. The undercut formations (36) are resiliently deformable so that the elongate members (18) can be inserted between them into engagement with the locking formations. |
