Abstract
Abstract A self-locking buckle for straps, belts, bands or ties formed of a one-piece unit having two sections, one folded over the other to form a first strap connection at the juncture of folding and a second adjustable strap connection adjacent corresponding free ends of the folded unit. The latter connection is adapted to receive one end of a strap threaded over one free end of the unit and beneath the other free end reversely upon itself for longitudinal sliding adjustment of its effective length relative to the buckle and automatic locking at preselected positions of the adjustment.
