A clothes-pin (also C47, bullet, clothes peg, or just peg) is a fastener used to hang up, and dry clothes, usually on a clothes line. Pegs often come in many different designs.

Today, many pegs are manufactured very cheaply by creating two interlocking plastic or wooden prongs, which in between is often wedged a small spring. By a lever action, when the two prongs are pinched at the top of the peg, the prongs open up, and when released, the spring draws the two prongs shut, creating the action necessary for gripping.

Older designs do not use springs, but often are fashioned in one piece, with the two prongs part of the peg chassis with only a small distance between them - this form of peg creates the gripping action due to the two prongs being wedged apart and thus squeezing together in that the prongs want to return to their initial, resting state. This form of peg is often fashioned from plastic, or originally, wood.

Filmmaking

In the film industry, during the production of a movie, commercial, music video, etc., a spring-type clothes-pin is called a "C47", "C74", "47", "peg" or "bullet". It is incredibly useful on the set. Lights used on film sets quickly become far too hot to touch. As a result, a wooden C47 is used to attach a color correction gel or diffusion to the barn doors on a light.Box, Harry (1993) (1st ed). Set Lighting Technician's Handbook. Focal Press. p 141, 347, 349. ISBN 0-240-80161-X. The wooden clothes-pins do not transmit heat very effectively, and therefore are safe to touch, even when attached to hot lights for a significant period of time. Plastic or metal clothes pins are not used as plastic would melt with the heat of the lights and metal would transfer the heat making the clothes-pin too hot to touch. People like gaffers, grips, electricians and production assistants may keep a collection of C47’s clipped to clothing or utility belt at all times.Rahmel, Dan (2004) Nuts and Bolts Filmmaking: Practical Techniques for the Guerilla Filmmaker Focal Press. p. 196. ISBN 0-2408-0546-1 Hence the nickname "bullet", as so many crew members clip a number of C47s to their utility belts, much like an old west gunslinger would carry extra bullets on their gun belt.

Clothes-pins are also used for straws. When a talent is in full makeup they often times can not drink from a cup so they drink from a straw. When the bottle or cup is to deep for the straw a C47 is clipped an inch from the top of the straw to keep the straw from falling into the drink.

The name "C47" may have come from an attempt to make it sound less mundane than a clothes-pin, or it may have come from the label on the bin used to store them in an early studio.Uncommon Goods Uncommon Knowledge Retrieved July 14, 2006. More commonly believed is that the name "C47" came to be the designation that the clothes-pins were given when printed on studio budgets to trick budget managers into approving the request for them. A "C74" or "74C" is a clothes-pin that has been taken apart, reversed, and put back together so that the small end comes together. This gives a tweezer-like tool.
