Abstract
A spring fastener of generally V-shaped configuration and including a first, substantially monoplanar leg joined to a second substantially monoplanar leg through a bend portion defining an acute angle of from about 43.degree. to about 48.degree.. The second leg defines a circular aperture therethrough, and the first leg has a tongue pressed out of a central portion thereof, and projecting toward said second leg at an acute angle to said first leg. The tongue projects a distance from the plane of the first leg, as measured normal to that plane, which is from about one-half to about two-thirds of the total distance of projection of said bend portion from the plane of the first leg, also as measured normal to the plane of said first leg. The invention also includes and relates to fasteners of the type described in combination with a synthetic resin box which has an open side. The box carries a pair of the fasteners by having the described first leg of each fastener pressed into an accommodating slot in the box. The box further defines an elongated passageway adjacent each of the slots and extending parallel to the slot and the first leg of the respective fastener. The second leg of ea…
