  • Publication number: 20150226245
    Abstract: The present invention relates to an elastic band end fastener connecting structure, including an elastic band and a fastener, wherein the fastener includes a clamping piece and a ring buckle. A section of the said clamping piece has a C-shaped structure. Flattened clamping piece can hold both ends of the folded elastic band to form a first end connecting structure. The folding point in the middle of the elastic band forms a second end. The ring buckle is bent into a rectangular shape by steel wire. Both ends of the steel wire are mutually staggered in the center of the rectangle, so as to form staggered gap, to reach the folding point of the elastic band with the aid of the staggered gap, and to form a second end connecting structure of the elastic band. The present invention provides the clamping piece and ring buckle with a simple structure, that facilitates tying or affixing the elastic band to a preset fixed ring of an object, and that simplifies the assembly process, and reduces the maintenance cost.
