Abstract: A clasp for jewelry chains which comprises a hook and separate keeper member, the hook and keeper members being attached to respective opposite ends of the chain. The keeper member has a curved channel segment conforming in shape to a curved segment of the hook member such that the hook member is slid within the channel section and held in place by dynamic tension, while a shank section of the hook member is snap-fitted between two spaced-apart shoulders formed in a mouth portion of the keeper member to securely hold the hook and keeper member together.
