A binder clip, or a banker’s clip or foldover clip, 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. The term bulldog clip is used in the United Kingdom to describe both this invention and an older device with the same function, which is stronger and has rigid rather than folding handles. It is also sometimes referred to as a “handbag clip” because, when not in use, its clip can be up to look like a handbag.
