ABSTRACT:
A threaded attachment provides means of applying external threads to elongated members, such as tubes, rods, cables, and the like. The threaded attachment can be expanded to install around an elongated member. When the threaded attachment is compressed or closed around the elongated member, an adhesive liner on the inside surface of the threaded attachment bonds the threaded attachment concentrically to the elongated member.
