ABSTRACT:
A magnetic fastener is provided with a female member having a slide plate which engages with a recess portion of a projection formed in a cooperating male member. The projection is held in engagement with the slide plate via a permanent magnet formed in the projection. The female member has first and second plate members sandwiching the slide plate. The first and second plate members are held together by deforming the plate members or by welding. The first and second plate members and the slide plate each have an opening, the slide plate having a larger opening. The projection is inserted into the opening upon which one edge of the slide plate formed by the opening engages the recess portion and held thereto via the magnetic attraction. The male member can only be disengaged from the female member by pushing or pulling its engaged edge away from the projection.
