A hook-and-eye closure is a clothing fastener that consists of two parts, each sewn to their respective pieces of cloth, one with a small protruding blunt hook, and the other with a small loop (also known as the "eye" or "eyelet") protruding. To fasten the garment, the hook is slotted into the loop.
Hook-and-eye closures are typically used in groups to provide sufficient strength to bear the forces involved in normal wear. For this reason, hooks and eyes are commonly available in the form of hook-and-eye tape, consisting of two tapes, one equipped with hooks and the other equipped with eyelets in such a way that the two tapes can be "zipped" together side-by-side. To construct the garment, sections of hook-and-eye tape are sewn into either side of the garment closure.
Hook-and-eye closures are commonly used in corsetry.
