Description

ABSTRACT OF THE DISCLOSURE A molded sliding bar buckle of the type comprising a strap retainer bar slidably mounted on an open rectangular connector frame having a grip base and a connecting bar on opposite sides of the strap retainer bar. The strap retainer bar includes a central strap engagemnt portion for retaining theraround one end portion of a strap and having on its back a sloped flat surface facing away from the grip base. The sloped flat surface has an upper end disposed adjacent to the connecting portion and a lower end disposed adjacent to the grip base, the upper end lying in a plane extending through a center of the thickness of the strap engagement portion. With this construction, when the strap is longitudinally tensioned with its one end portion looped around the strap engagement portion, a tensioning force is transformed substantially into a force or a vector acting on said plane in a direction to tend to move the strap retainer bar linearly toward the grip base. A component of the tensioning force which acts on the strap engagement portion to rotate the strap retainer bar is substantially negligible. Thus, the strap end is held firmly against displacement.
