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 brand of clip. For the clips also referred to as a "binder clip", see Binder clip.

Alternative uses

Bulldog clips have many uses, domestic, industrial and in arts and crafts.

Bulldog clips are a good tool for making flicker books as they allow sheets to be added, removed or replaced.[1]

A novel use for this product is to use it as a wire guide at a computer station for example. 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.

Another use is for resealing an opened bag of food to keep it fresh longer.

Bulldog clips can be used in weaving to warp a loom.[2]

Bulldog clips can be used to make a fast release mechanism for theatre "drops".[3]

An eraser held in a Bulldog clip can, by providing a larger surface to grip, be useful to some people with motor disabilities.[4]

A clip can be used to hold down the Ctrl key on a computer keyboard to circumvent the issue of holding the button down when selecting multiple items.

A clip can be used to pin hair back on top of a person's head.
