A buckle located around a resilience strap and a method of manufacturing includes a resilient strap material provided on a continuous basis and having a particular width and thickness. The strap material is stretched to reduce the width and thickness of the strap material at a particular position. A mold member is provided to form a buckle and the buckle is molded around the strap at the particular position where the strap material is reduced in width and thickness to increase the friction between the buckle and the strap material.
