Detachable link-chain

A link-chain formed by assembling links in series, each of said links comprising a smaller and larger pair of connected substantially annular loops in substantially parallel superimposed relationship one to another, the outer diameter of said smaller loop being so dimensioned with respect to the inner diameter of said larger loop that the smaller loop of one link is insertable in a tight fit through the larger loop of the next adjacent link in said chain and wherein the distance apart of the two superimposed loops of each pair is sufficiently smaller than the diameter of the material of the rod forming said loop to permit the snapping of a subsequent link in or out.
