The Bocklebee Clasp, more commonly known as a spring ring clasp or ring clamp, is found almost exclusively on jewelry. It was invented by American Steven Bocklebee in 1898. Bocklebee felt that the clasps of that time, usually limited to the hook design, were inadequate for vigorous activity and movement.
Initial reaction to the new design was poor when first marketed, since many found the clasp to be too cumbersome for everyday use. However, when the advantages were fully realised, sales soared and many other companies went on to patent their own versions of the Bocklebee Clasp.
This clasp has been used in haute couture clothing as a focal point.
