ABSTRACT:
A keeper for detachably attaching the two ends of a length of flexible linear solid chain, such as a necklace or a bracelet, to each other. A spherical ball at one end of the chain is inserted into a deformable clamp which is attached to the other end of the chain. The clamp has two arms which detachably engage the ball. A frusto-conical keeper element is freely mounted about the chain length adjacent the clamp; the keeper element converges and tapers away from the clamp, so that when the clamp with engaged ball is displaced into the keeper element by concomitantly pulling the keeper element and the other end of the chain away from each other, the clamp and engaged spherical ball are tightly fitted into the keeper element. The outer surface of each curved arm of the clamp thus engages the inner surface of the keeper element, so that the two chain ends are detachably attached to each other, and cannot be separated from each other, except by pulling the one end of the chain length away from the keeper element.
