The name of the belt fastener varies depending on the type of belt and the fastening mechanism used. There are several types of belt fasteners, each with its unique design and function.

One common type of conveyor belt clamp fastener is the buckle, which is used to fasten belts made of leather, cloth, or other materials. Buckles come in different shapes and sizes, and they can be made of metal, plastic, or other materials. The most common types of buckles are the single-prong, double-prong, and snap buckles.

Another type of belt fastener is the clasp, which is commonly used in jewelry belts and waist belts. The clasp consists of two interlocking parts that snap together to hold the belt in place. Clasps are often made of metal, but they can also be made of other materials like plastic or wood.

A third type of belt fastener is the hook-and-loop fastener, which is commonly used in athletic belts and waist belts. The hook-and-loop fastener consists of two parts: a strip of small hooks on one side and a strip of loops on the other side. When pressed together, the hooks and loops interlock, holding the belt in place.

Another type of belt fastener is the zipper, which is commonly used in belts that have pockets or compartments. The zipper consists of two rows of interlocking teeth that are pulled together by a slider.

When the slider is moved up or down, the teeth interlock, holding the belt in place.

Finally, some belts have no fastener at all and are instead designed to be tied or knotted around the waist. These types of belts are common in traditional clothing and costumes, and they can be made of cloth, leather, or other materials.

In summary, the name of the belt fastener depends on the type of fastening mechanism used. Common types of belt fasteners include buckles, clasps, hook-and-loop fasteners, zippers, and ties or knots.

Each type of fastener has its unique design and function, and choosing the right one depends on the type of belt and the desired level of security and ease of use.
