ABSTRACT:
A jewelry article includes an elongated support and a multiplicity of beads strung along the support. At least one of the beads constitutes a locking bead consisting of a substantially closed hollow shell with a pair of aligned holes sized to slideably receive the support. A heat-shrinkable plastic tube is positioned inside the shell with its opposite ends captured by portions of said shell around the holes. The tube has a heat-deformed inner wall which substantially conforms to the support so as to permanently anchor the bead to the support. A method of stringing the locking bead is also disclosed.
