Abstract: A jewelry clasp for a jewelry band having chain-link terminals comprises releasably interlockable male and female clasp members. Slip-on connection means are rigidly secured to the distal ends of the male and female members to provide a solderless arrangement for attaching the chain-link terminals of the clasp. Each slip-on connection means is formed from a helix having approximately 11/2 coiled turns so as to form an entrance opening into which the chain-link terminal can be inserted into linking engagement and secured without soldering or special tools. A rectangular blank for making the male clasp member includes an end notch for receiving the helix to be rigidly secured and a laterally projecting leg adjacent thereto adapted to become bulbous when heated and thus form the pin portion of a safety latch.

Abstract: A jewelry clasp for a slender, elongated, band--e.g., a necklace, bracelet or the like--comprises male and female members respectively attachable to the band terminals; the female member being tubular and the male member having a detent with a projecting tongue and with a spring leaf, constituted by a distal extension thereof, folded to overlie the tongue in angular relation therewith; being deflectible to lie flatly against the tongue to permit its passage through a narrow diametrical slot in an end closure of the female member; said leaf then rising off the tongue in the interior of the female member to engage the inner face of the end closure preventing withdrawal of the male member therefrom and also becoming wedged against the progressively narrowing inner walls of the female member to inhibit wobbling of the male member therein; a fin projecting through a slot in the wall of the female member being manipulable to depress the leaf to permit withdrawal of the detent from the female member.
