Abstract: A jewelry clasp has a base with a base end and a distal end with a hook extending back over the base. A jaw is moveably mounted with respect to the base adjacent a midpoint. A retainer portion of the jaw is adapted to overlie the top of the hook adjacent the distal end. A closed space is formed between the jaw, the hook and the base to receive an eyelet. A lever portion on the end of the jaw opposite the hook is provided to move the retainer portion outwardly in order to open the clasp. Preferably, a pivot pin mounts the jaw and a spring is utilized to urge the retainer portion firmly against the hook. The hook can have a straight section engageable by the eyelet during coupling and a curved section at the top of the hook. Particular angle positioning can provide additional assistance in coupling and decoupling the eyelet, along with the positioning, curving and spacing of the tip of the jaw. Alternatively, the hook may be curved substantially throughout its length.
