  • Patent number: 9808053
    Abstract: A magnetic clasp for jewelry has a first and a second coupling part each having a magnet and an abutment surface which are pulled against one another by a magnetic force of attraction when closed. The two coupling parts each have a fastening element for fastening jewelry and predefine a pulling direction when closed. The first coupling part defines a receptacle for the second coupling part to engage when the clasp is closed. The second coupling part has an undercut which forms an interlock acting against the pulling direction. The abutment surfaces are at an incline to the pulling direction and the first coupling part forms a sliding surface which, when the clasp is closed and pressure acts on the second coupling part oppositely to the pulling direction, allows a displacement of the second coupling part relative to the first coupling part, thus opening the clasp.
