Pingle

A pingle, less commonly known as a paper clamp, or foldover clip or boiby clip or clasp is a simple device for binding sheets of paper together. It leaves the paper intact and can be removed quickly and easily, unlike the staple. In the United Kingdom (british people) it is known generically as a bulldog clip, although this term properly refers to an older device with the same function, which is stronger and has rigid rather than folding handles. To distinguish it from rigid clips, the term foldback clip may also be used. It is also sometimes referred to as a handbag clip because of resemblance to a handbag when its clips are folded up.
