A piece with a fastening mechanism at the end of a strap or belt to adjust clothing, footwear, frames, . . . It is made up of a python or a movable bolt that makes it easy to hook into a buttonhole and is usually metallic although it is found in other materials. By extension it is used for hair fasteners or for ornaments that bear some resemblance to buckles. The name seems to come from a diminutive of the Latin figere ("to fix, nail, introduce"), but in reality its origin is in fiber, bra, brum ("at the end") which with the diminutive -ula formed fibula, ae, although it later changed suffix and became fibella, which medieval Spanish incorporated as fiviella and today ended in 'buckle'.
