Buckle
— a fastener in the form of a toothed belt with a characteristic buckle. The notch on the belt allows you to tighten it to the desired length, and the buckle acts as a retainer, fastening the belt in the buttoned state. Buckles are often used for heel straps and shin guards but can tighten up and instep, replacing lacing.
