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.

A spring clip in the form of a generally U-shaped clamp for holding sheet material, comprising: two substantially flat holding members, each holding member including parallel side edges, a front end, and a rear end opposite said front end; and a rear bight joining member; said rear bight joining member being connected to and between said rear ends of said holding members, and resiliently biasing said front ends of said holding members together with a predetermined clamping force such that said front ends are adjacent to each other; each of said front ends of said holding members being folded over outwardly away from its corresponding holding member and toward said rear bight joining member, forming a J-shaped outer channel including an inner side portion and an opposite outer side portion connected by a base portion, said inner side portions adapted for contacting said sheet material when said sheet material is inserted within said clip; each of said base portions of said channels including cuts therein at opposite ends thereof which extend for a predetermined distance from the side edges of its corresponding holding member, forming slits in each base portion at said opposite ends thereof.
