To provide such clasp suitable as button for clothes, buckle for belt or the like adapted to ensure its reliable fastening. A pair of basic bodies connected to front ends of a pair of swingable arms, respectively, contain therein magnets having opposed poles, respectively. These basic bodies are provided with at least one set of mutually opposed protruberances and notches adapted to come in engagement with each other as the front ends of the swingable arms get nearer toward each other and thereby to prevent the pair of basic bodies coupled to each other under attractive effect of the magnets from moving in horizontal direction as well as from swinging away from each other. Of the pair of basic bodies coupled to each other in vertical direction, the upper interlocking element may be depressed downward to move the front ends of the respective arms and thereby to disengage the protruberance from the notch.
A clasp comprising a pair of swingable arms, a pair of basic bodies connected to front ends of the respective arms and magnets mounted on the respective basic bodies so that the pair of basic bodies may be detachably coupled to each other under mutual attraction of these magnets, and
