Abstract: A buckle for securing plastic strapping around an object. A pair of independently movable fingers are hingedly mounted by flexible plastic strips in spaced relationship on a rectangular base. The base has spaced pairs of integral side and end members which form a rectangular aperature therebetween. The fingers are adapted to be folded into superimposed, overlapped position along the side frame members. A post is formed on each of the end members at the midpoints thereof.
