An assortment of binder clips, with an AA battery for scale.

A single, large sized binder clip.

A binder clip is a simple device for binding pieces of paper. A binder clip is a strip of sheet steel bent into the shape of an isosceles triangle with loops at the apex. Tension along the base of the triangle forces the two sides closed, and the loops prevent the sharp steel edges from cutting into the paper. The loops also serve to hold two pieces of stiff wire, which serve as handles and allow the clip to be opened. The two slots cut in each loop are cleverly shaped so that the wire handles can be folded down once the clip has been attached, and the spring force of the wire holds them down on the surface of the paper. This holds the clip relatively flat, for easier stacking (see upper right corner of the photo). The handles can also be removed altogether by squeezing them sideways and pulling them out.
