A belt cl is a fastening device designed to secure and adjust the fit of a belt around the waist. It typically consists of a metal or plastic buckle, often in the shape of a rectangular or circular frame, with a hinged bar or prong that fits through the holes on the belt strap. When the bar is inserted into one of the holes, it locks the belt in place, preventing it from slipping or coming undone. The belt cl provides both functional and aesthetic value, as it not only keeps the belt securely in position but also adds a stylish touch to the overall look.
