Velcro is a brand of versatile fastening devices, known as hook-and-loop fasteners, hook-and-pile fasteners, or touch fasteners, that allow two surfaces to be repeatedly attached and detached with ease. A trademark of Velcro Companies, the brand name is often used generically to refer to this type of fastener. Invented in the mid-20th century, it is widely used in clothing, accessories, and various industrial and consumer applications. The fastener consists of two complementary components: one with tiny hooks and the other with soft loops. When pressed together, the hooks catch the loops, creating a secure but temporary bond. The fasteners can be separated by peeling or pulling the surfaces apart, often producing a distinctive ripping sound.
