Abstract
According to the present invention a spring clip comprises a holding portion No. 1 made from a resilient strip with one or more than one slits and stamped portion therein permitting turn over motion thereof and another holding portion No. 2 opposed to the holding portion No. 1. In contrast with a conventional spring clip, the disclosed clip is compact, since it has no levers pivoted to the leading ends of the holding portion or extended from the holding portions. The disclosed clip is advantageous, since the leading ends are wide enough to clip sheets firmly.
