Abstract: There is described a security sealing system for selectively immobilizing two relatively movable parts, the system comprising a housing, a tunnel, into one end of which a seal element may enter, to latch resiliently with an insert which enters the tunnel from its other end. The device is applicable to postal envelopes, cabinets, freight containers etc.

Abstract: A jewelry clasp having a main body formed by a pair of symmetrical members mounted in a parallel spaced relation to form a laminated structure, each member including a closed loop at one end and a partial loop at the other end, the closed loop being connected to one end of a decorative chain and the partial loop being detachably connected to the other end of the chain and a detent type latch assembly mounted on the main body for locking the other end of the chain on the partial loop.

Abstract: A clasp or buckle is disclosed for several chains, strings of beads, pearls and like jewelry whereby the chains or strings may be arranged and fastened into various ornamental and multi-stranded closed loop configurations at the option of a user of the jewelry. The clasp or buckle includes a substantially hollow main buckle member having two parts hingedly attached to one another. The main buckle member receives and removably mounts a plurality of connecting members in a substantially parallel, substantially regularly spaced configuration. Ends of the connecting members form hooks, loops or eyelets to which respective ends of the chains or strings of beads, pearls and the like can be mounted.

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: An interchangeable end piece member for removably connecting a watchband to a wristwatch case so as to accommodate watchbands universally to watchcasings having various spacings and configurations between the lugs for spring bars of different lengths. The end piece member has at least one tongue which slides into a mating longitudinal groove in a retainer clip attached to the watchband. A resilient tab locks the tongue in the groove, with means to release the tongue by deflecting the tab.
