Abstract

Abstract A buckle cooperating with two straps each having a hooked end and a free end for fastening goods on a truck or the like. The buckle has a body and two rings. The body has two rectangular walls each having two longitudinal slots at two opposite ends thereof, two clefts each communicating with one of the slots, and at transverse middle cutoff. The walls are connected to each other with two bars below the slots and a flat element below the cutoff, thereby forming two openings beside the flat element. Each ring has a flat member. The hooked end of each strap is attached to a different side of the truck. The free ends of the straps are (a) inserted through the openings, (b) wound around the flat members of the rings, (c) inserted between the flat members of the rings and the bars, and (d) disposed between the bar and the strap. The flat member has an unlocking position where the strap can be pulled and a locking position where the strap is locked.
