The present invention relates to fastening devices and relates more particularly to a fastening device for fastening a key chain to one'waist belt or clothes.
Key chain is a device commonly used holding a bunch of keys. When in use, people tend to attach a key chain to one's waist belt or clothes by a clip or clamp. FIG. 1 illustrates a known structure of key chain clip for fastening a key chain to one's waist belt or clothes. This structure is not satisfactory in use because the teeth of the clip may damage one's waist belt or clothes easily when it is in use. FIG. 1--1 illustrates a known structure of R-shaped clamp for fastening a key chain to one'waist belt or clothes. This structure is still not satisfactory in use due to weak clamping force.
