The safety pin, also known as a baby pin, is a variation of the regular pin which includes a simple
spring mechanism and a clasp. The clasp serves two purposes: to form a closed loop thereby prop
erly fastening the pin to whatever it is applied to, and to cover the end of the pin to protect the us
er from the sharp point.
Safety pins are commonly used to fasten pieces of fabric or clothing together. They were widely
used to fasten cloth diapers (nappies), as the safety clasp prevents the baby from being jabbed.
Similarly, they can be used to patch torn or damaged clothing. Safety pins can also be used as an
accessory or jewelry, such as earrings, chains, and wristbands. Sometimes they are used to attach
an embroidered patch.
