Abstract
A spring clip for binding a material, such as papers, is formed of a pair of grasping portions and a connection portion for connecting the grasping portions. Each grasping portion has a trapezoid form surrounded by front and rear edges and two side edges. Also, each grasping portion has a flat outer surface, a flat inner surface and an inclined end surface at a free end or the front edge. When the grasping portions abut against each other, the inclined end surfaces form a gap therebetween. The clip is applied to the material by a clip driver formed of a casing for receiving the clip, and a knob for pushing the clip. A pair of clip opening spring members is attached to the casing for opening the clip when applying the clip to the material.
