Abstract: A strapping system and buckle therefor comprising a planar frame with a pair of parallel end legs connected by a pair of parallel side legs to define an opening therebetween, and a bridging legl connecting the side legs with an opening between the bridging leg and the two end legs, respectively, of suitable dimensios to thread a strap therethrough with the bridging leg disposed between the threaded strap, and wherein one end leg is extended to hold permanently one end of the strap, the other end being threaded through the buckle. Advantageously, the buckle is of a unitary structure which can be easily and inexpensively manufactured, and utilizes only a single bridging leg having at least a part thereof above the planar frame together with suitable dimensions of the openings between the bridging leg and end legs to lock the strap threaded therethrough.

Abstract: A strapping system using a novel buckle werein one end portion of the buckle is attached to one end of a strap, and the other end of the strap is threaded through the buckle in such a manner that the strap is held securely in place. The buckle is of a unitary structure comprising the end portion and threading portion in which are located two outer parallel legs and a center leg with gaps therebetween, and wherein the center leg has roughened surfaces and edges which are 90.degree. and one outer leg having a 90.degree. edge and roughened surfaces so that the threaded strap contacts the 90.degree. edges of the center leg and the 90.degree. edge of the one outer leg so that the strap is securely held by the buckle.

Abstract: A buckle for fastening together the ends of a flat plastic strap, comprising in a unibody construction a pair of parallel ends a pair of parallel side legs disposed between the parallel ends, and a pair of parallel intermediate legs disposed between the parallel side legs with the intermediate legs having a rough top surface and a rough bottom surface, and the side legs have rough bottom surfaces, and constructed in such a manner that one end of the strap is threaded between the two intermediate legs, over the top surface of one intermediate leg and one side leg and under the bottom surface of one side. leg, with the other end of the strap being similarly threaded on the other intermediate leg, whereby the buckle holds tightly the strap after the ends are pulled tightly with the rough surfaces holding the strap and the strap being threaded so as to have four 90.degree. bends at the leg corners to enable better holding by the buckle of the strap in the tightened position.
