Abstract
A spring fastener or clip of generally V-shaped configuration and including a first, substantially monoplanar leg joined to a second, substantially monoplanar leg through a bend portion so that the legs define between them an acute angle from about 43.degree. to about 48.degree.. The second leg has a circular aperture formed through a central portion, and the first leg has a tongue or tine pressed out of a central portion of the first leg and projecting generally toward the center of the aperture in the second leg, and at an acute angle of from about 22.degree. to about 28.degree. to the plane of the first leg. The tongue projects a distance from the plane of the first leg, as measured normal to that plane, and so as to include the thickness of the first leg, which is from about one-half to about two-thirds of the total distance of projection of the bend portion of the fastener from the plane of the first leg, also as measured normal to the plane of the first leg, and so as to include the thickness thereof. The invention also includes and relates to fasteners of the type described in combination with a synthetic resin box which has an open side, and which has a cover plate secured …
