PROBLEM TO BE SOLVED: To provide an accessory clasp capable of surely connecting an accessory only by a simple insertion operation, after that, eliminating any possibility of careless separation and having a simple structure. SOLUTION: When a columnar projection portion 11 of a male clasp 1 is inserted into a female clasp 2 at an optional relative angle in the circumferential direction, its end 11a abuts on fitting portions 31 of a spring member 3 exposed to the interior of a bore 21 of the female clasp 2, the columnar projection portion 11 is rotated by a guide face 13 to guide the fitting portions 31 to grooves 12, the fitting portions 31 are fitted in the pair of grooves 12 respectively to prevent the slipping-off of the female clasp 1 from the male clasp 2. When the male clasp 1 is axially rotated with respect to the female clasp 2 substantially 90°from the connection state, the fitting portions 31 of the spring member 3 are detached from the grooves 12, so that a user can pulls out the male clasp 1 to separate it from the female clasp 2.
