Abstract: A clasp mechanism that incorporates an extensible feature for ease of use is provided, which can be used on jewelry and other items. Instead of completely separating the ends of the attached jewelry or other item and then having to reconnect a clasp, the clasp mechanism separates and spreads apart by an interconnected extensible segment. The clasp can be attached to opposing ends of nearly any jewelry item, such as a bracelet, by known techniques such as soldering or bonding. The clasp incorporates an extensible segment such that when connected to opposing ends of a bracelet for example, the bracelet expands at the clasp mechanism to fit over a hand or foot and then contracts to securely fit at the wrist or ankle. The clasp mechanism does not require disconnecting and reconnecting when placing the jewelry piece onto one's person.
