Abstract: A clasp which is lockable in both an open and a closed position includes a body having a first opening, a second opening, and an internal space; a connector fixed to the body for linking to a chain; a first spring; and a moveable connector. The movable connector, inseparable from the body, is movable to a locked closed position by the first spring and movable to a locked open position by an external force. The movable connector includes a first latch piece within the internal space of the body, and extends through the first opening. A button extends through the second opening. The button includes a second spring and a second latch piece that interfaces with the first latch piece. In a first position of the button, the second latch piece locks with the first latch piece.

Abstract: A clasp is described that is lockable in both an open and a closed position. In the locked open position the clasp can be manipulated without concern for the clasp unintentionally closing before it can receive the end of a chain, such as a necklace or the like. Pushing a button on the clasp closes and locks the clasp. The clasp remains locked in the closed position until the button is pressed and the clasp is pulled open.
