Abstract:
1. A fastener for connecting together two pieces of which at least one is a textile, the fastener comprising: a front element having a catch ring forming a generally cylindrical backwardly open seat cavity, and having a pair of catch faces directed away from one end of the front element, flanking the seat cavity, and angled such that front edges of the catch faces are closer to the one end than back edges of the catch faces, a plurality of forwardly projecting pins, a front holder through which the pins pass, and a disk-shaped sealing element between the catch ring and the front holder and having a plurality of openings through which the pins pass; a front magnet held by the front holder in the front element immediately forward of the seat cavity; means for connecting the one end of the front element to one of the pieces to exert traction on the front element and magnet in a direction toward the one end; a back element formed with a forwardly projecting generally cylindrical bump loosely fittable in the seat cavity, the back element having a pair of catch faces generally complementary to the catch faces of the front element and engageable in the direction therewith on engagement of the bump in the seat cavity; means for connecting an end of the back element to the other of the pieces to exert traction opposite to the direction on the element away from the one end of the front element; and a back magnet secured in the bump, the magnets being so polarized as to attract each other and pull the bump into the seat cavity on juxtaposition of the front and back elements.
