ABSTRACT OF THE DISCLOSURE A molded strap fastener of a generally rectangular shape includes a first cross bar for retaining therearound a looped one end portion of a strap, a retainer poretion disposed laterally adjacent to the cross bar and frictionally engageable with the strap end portion, and a second cross bar fixedly connected to the other strap end. The first cross bar includes a pair of diametrically opposite sharp corners and the ratainer portion has a sharp corner, these sharp corners serving as stops to retain the strap in position against accidental displacement even under heavy tensioning forces. To provide a greater resistance to strap loosening, the first and second cross bars lie in different levels so that a rotational force is created upon the fastener when the latter is in actual use, which force growing greater the larger the tension and thus urging the retainer portion to firmly grip the strap end at its sharp corner. This gripping is further enhanced by the retainer portion which projects beyond the bottom surface of the fastener.
