Buckle classification

A buckle (from Latin buccula) is a clasp used for fastening two things together, such as the ends of a belt, or for retaining the end of a strap. Before the invention of the zipper, buckles were commonly used to fasten boots and other shoes.

Buckles can also be seen on backpacks, watches and other wrist jewelry, or for ornamental purposes on other various objects. Buckles are also commonly seen in modern gothic fashion.

Buckles are seen of completely different design, buckles usually made of plastic that fasten onto a strap in two places and clip together, are increasingly used.

A belt buckle is a buckle, a clasp for fastening two ends, as of straps or a belt, in which a device attached to one of the ends is fitted or coupled to the other. Clasp type belt buckets have been in common use in Europe for at least 1,500 years but the time and place of origin is unknown.

In the United States, removable, ornamental belt "buckles" that generally attach to the original buckle are common.
