Buckle

A fastening device used to join two ends of a belt, strap or the like. It may be a single unit designed to be attached to one end of a belt or strap and secure the opposite end by penetration, by clamping, or by friction, or it may consist of male and female sections having one section attached at each end of the belt or strap and joins the two ends by a hook-like or other interlocking action.
