Abstract: The object of independent claims 1 and 3 relates to a magnetic clasp consisting of disk-shaped closure bodies, at least one of them being a permanent magnet, and one of the two closure bodies being developed as annular disk open on both sides. The first embodiment of the magnetic clasp has another body of magnetizable metal which is inserted with radial clearance into the two open annular disks, while the second embodiment of the magnetic clasp has only one open annular disk which is provided with a slot and into which the other closure body, developed as closed disk, is inserted with clearance in axial direction via the slot.By these embodiments of the magnetic clasp there is created a construction which is protected against unintentional opening by exerting a pulling action on the closure bodies. Furthermore, since in both embodiments the clasp is open in axial direction towards both sides, the closing and opening thereof is substantially facilitated.
