ABSTRACT:
A strap fastener or buckle for connecting ends of a strap, belt or the like is adapted to enable adjustment of the effective length of the strap. The strap fastener is formed from a plastic material into an integrally molded structure having a grip head portion at one end and a connecting portion at the opposite end, these portions being connected by a pair of side flanges. A pair of spaced parallel cross bars extend between and are connected to the side flanges. The grip head portion has a sharply cornered bottom edge which serves as a stop for the strap. The cross bar which is disposed adjacent to the grip head portion has a plurality of sharp corners defining stops for the strap, one of the corners being disposed adjacent to the grip head portion and being spaced in plan view from the bottom edges by a distance larger than the thickness of the strap. The strap fastener is thus provided with multi-point stops along the path of the strap so that the strap can be retained firmly in place under heavy tension.
