What is a "buckle"?

A buckle is a fastener that is used to secure two ends of a strap or belt. It usually consists of a frame or a loop with a tongue that goes through it and is fastened securely with a pin or bar. Buckles can be made of various materials such as metal, plastic, leather, or even wood, and can be adorned with precious stones, rhinestones, or other embellishments to add an aesthetic touch. Buckles have been used for centuries as a practical means of securing garments and accessories, such as shoes, belts, and bags, and are still widely used today in fashion and other industries. They come in different shapes and sizes and can be designed to be simple or ornate, depending on their intended use and the desired style.
