ABSTRACT:
A very safe buckle, formed of plastic, is provided which enables a strap to be inserted and clamped easily and quickly, and which prevents the strap from being inadvertently loosened or pulled free of the buckle no matter how the strap or the buckle is pulled about. The buckle is comprised of two adjacent bars spanning the space between the sides of the buckle. The strap is passed between the two bars. One of the bars is rotatable and has a polygonal cross-section, the arrangement being such that the rotation of the rotatable bar reduces the size of the gap between the rotatable bar and the other bar, which is fixed, thereby clamping the strap securely between the bars.
