ABSTRACT:
This invention relates to a device or clip 10 for holding sheets of paper comprising a main body 11 and a flexible element 12. The element 12 consists of a strip of flexible material having pointed arms 13, which can be threaded through holes in the paper prior to passing through apertures 14 in the body 11, so the paper can be held between the element 12 and the base 15 of the body 11. A lid 16 is hinged along one edge of the base 15 and when closed it covers the bent over arms 13 preventing their withdrawal through the aperture 14, while also protecting the user from the sharp ends 20 of the arms 13.
