1. A threaded attachment for application on an elongated member, comprising:
a) a sleeve with helical threads on its outside diameter and with a longitudinal gap for its full length, and
b) a liner adhesively bonded to the inside surface of said sleeve,
whereby said gap can be expanded sufficiently to allow said sleeve and said liner to fit over said elongated member,
whereby said sleeve and said liner can subsequently be compressed so that said liner contacts said elongated member and adhesively joins said sleeve concentrically to said elongated member, and
whereby said elongated member is therefore configured with external threads.
