<p>A one-step fabric fastener has a front element formed with a backwardly open seat cavity holding a magnet 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. The one end of the front element can exert traction on the front element and front magnet in a direction toward the one end. A back element formed with a forwardly projecting bump holding a back magnet is loosely fittable in the seat cavity has a pair of catch faces engageable in the direction with the front-element catch faces on engagement of the bump in the cavity. The magnets attract each other and pull the bump into the seat cavity on juxtaposition of the front and back element.</p> |
