PROBLEM TO BE SOLVED: To provide an clasp for accessory, which surely maintains the locking state between a clasp body and a coupling pin, enables the easy attachment of a locking member to the clasp body, which can be favorably adjusted to a compact size so that the clasp body can be used as a part of an accessary piece, and which can be manufacturized at a lower cost. SOLUTION: A clasp used for a ring-shaped accessary piece such as a necklace or the like consists of a clasp body and a coupling pin. The coupling pin to which one end of the ring-shaped accessary piece is connected is formed with a locking groove in a bar-like peripheral surface. The clasp body to which the other end of the ring-shaped accessary piece is connected includes: a locking member including a locking frame capable of being fit into the locking slot of the coupling pin and a pushbutton outside the clasp body; a detachment stopper mechanism for preventing the locking member from coming off the clasp body; and a built-in coil spring which urges the locking frame of the locking member in a direction in which the frame is always locked to the locking groove of the pin.
