Bulldog clip

A bulldog clip is a device for temporarily but firmly binding sheets of paper together. It consists of a rectangular sheet of springy steel curved into a cylinder, with two flat steel strips inserted to form combined handles and jaws. The user presses the two handles together, causing the jaws to open against the force of the spring, then inserts a stack of papers and releases the handles. The spring forces the jaws together, gripping the papers firmly.

This article is about a particular design of clip. For the smaller clips with folding handles sometimes referred to as bulldog clips, see Binder clip.

Alternative uses

Bulldog clips can be used in many domestic, industrial, and arts and crafts applications, including:

  • The binding of a flip book allowing sheets to be added, removed or replaced.[1]
  • A cable tidy at a computer station. The clip can be clamped onto the edge of a desk and computer cables can be threaded through the holes on the end of the tip. This helps the user organize wires and prevents them from falling back behind the desk.
  • Resealing an opened bag of food to keep it fresh longer.
  • Warping a loom when weaving.[2]
  • A fast release mechanism for theatre backdrops.[3]
  • Holding an eraser, providing a larger surface to grip for those with motor disabilities.[4]
  • Holding down a Ctrl key on a computer keyboard to circumvent the issue of holding the button down when selecting multiple items.
  • Pinning back hair back on top of a person's head.
