  • the fixing of the capsules (5, 10) by crimping their side walls (5D, 10D) forming a return (5C, 10C) on the rear bases (1 B, 6B) of the magnetic assemblies is given as non-limiting example. It can be understood that the capsule may have any specificity, in particular small tabs, in order to maintain the various constituent parts of the magnetic assemblies.
  • the magnetic closure device according to the invention being particularly intended to removably connect a first surface and a second surface of an article or accessory.
