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. | |
