  "claims": [
    "1. A fastener for accessories, which engages a female part located at one end of a chain accessory with a male part located at another end side of the chain accessory to lock them: wherein the female part and the male part comprise a female attraction part and a male attraction part respectively; wherein the female attraction part and the male attraction part have a part of a pair of magnets respectively or have a magnetic part and a metal part attracted to each other respectively; wherein the female attraction part and the male attraction part are located in a position to guide the female part and the male part to a correct position; wherein the female part is a crocodile clip comprising a pair of jaw members, which are able to open/close by a spring force; wherein the male part is a locking part, which is inserted and locked in a space between the pair of jaw members when they are in an open state; wherein the female attraction part is located in an inner space of the pair of the jaw members; wherein the male attraction part is located at a front part of the locking part; wherein the female attraction part, which is located in the crocodile clip, is set to either one of the pair of the jaw members; wherein the fastener for accessories comprises a holder, into which the male attraction part of the locking part is inserted, that is placed in front of the female attraction part; wherein the holder is located in one jaw member of a pair of the jaw members and an inner surface of the holder forms a guide surface, which is in almost parallel to a jaw member; and wherein the locking part slides along the guide surface of the holder when engaged/disengaged.",
    "2. The fastener for accessories according to claim 1, wherein an opening of the holder is directed towards a lateral direction, provided that an opening of the crocodile clip is directed towards a lateral direction; and wherein the inner surface guides a horizontal slide of the locking part in an inner space of the holder.",
    "3. The fastener for accessories according to claim 2, wherein the holder is a cylindrical holder, into which the cylindrical-locking part can be inserted.",
    "4. The fastener for accessories according to claim 3, wherein the guide surface is a continuous surface comprising an inner surface of the cylindrical holder and a notch surface, which is a semicircular insertion and is formed at the jaw member out of the pair of jaw members); and wherein the inner surface of the cylindrical holder is on a same surface of the semicircular insertion.",
    "5. The fastener for accessories according to claim 3, wherein a bottom half of the opening side of the cylindrical holder is interconnected with the semicircular insertion, which is formed at the jaw member out of the pair of the jaw members; wherein a top half of the opening side of the cylindrical holder is engaged/disengaged with the jaw member out of the pair of the jaw members; and wherein a stopping part is placed at a tip of the said jaw member."

  "description_excerpt": "The present invention relates to a fastener for accessories such as necklace, bracelet, anklet, key holder, bag, belt and the like.\n\nConventionally, various kinds of fasteners are used to fasten accessories such as a neckless. For example, a stopper having a magnet is disclosed (refer to Patent Document 1). The magnet is provided inside one of a pair of jaw members of a crocodile clip serving as a concave portion, and a magnet is provided at a distal end portion of the engaging member of the convex portion. And, a tip portion of the convex portion is guided into the crocodile clip of the concave portion by being affected by a magnetic force by locating the distal end portion of a locking member of the convex portion near a tip of the crocodile clip of an open concave portion, and the concave portion and the convex portion are locked.\n\nFurther, a clasp, which can be applied to an accessory, facilitates the mounting of an accessory, is disclosed (refer to Patent document 2). The clasp is easily connectable by one hand, and is further miniaturized.\n\nFurthermore, a clasp of an accessory of an accessory is disclosed in which a magnet is provided at a tip of a projecting piece, and a magnet for attracting a magnet of a projecting piece is provided at a back of an inserting hole (see, for example, Patent Document 3).",
