n. the buckle used to fasten a belt
Wikipedia
A belt buckle is a buckle, a clasp for fastening two ends, such as of straps or a belt, in which a device attached to one of the ends is fitted or coupled to the other. The word enters Middle English via Old French and the Latin buccula or "cheek-strap," as for a helmet. Belt buckles and other fixtures are used on a variety of belts, including cingula, baltea, baldrics and later waist-belts.
