Abstract
An article injection molded from a thermoplastic material, e.g., a polypropylene or acetal polymer, for use as a belt loop stay. A first strip is provided at each end with a flange. When unstressed, the first strip is straight, except for the flanges. A second strip, which is thinner so as to be more flexible, is joined integrally to the flanges, so as to form a closed loop. When unstressed, the second strip is bowed toward the first strip, between the flanges. The first strip has a stiffening rib, which stiffens the first strip against flexing on lateral axes. The second strip has several stiffening ribs, which stiffen the second strip against flexing on longitudinal axes but permit the second strip to flex on lateral axes. Beveled edges on the first strip facilitate insertion of a belt from either side of the first strip.
