Abstract
A spring clip in the form of a generally U-shaped clamp, the clamp comprising a pair of holding members for resiliently gripping sheets of paper or the like inserted therebetween. The holding members having forward or leading ends extending outwardly, folded back over themselves with J-shaped hook cross-section, and formed as outer lips portions of clamping jaws with the openings of the J-shaped hooks facing the rear ends of the holding members. The openings of the J-shaped hooks provide access to which leading guides of special opening applicator are engaged to open the normally closed clamping jaws. In contrast to the conventional spring clips of the similar type, the clip disclosed herein has no levers or widthwise, ear-like side projections for opening the clip is thus advantageous over the prior art devices because of its simplicity and ease in use.
