Western Union splice

Not to be confused with Lineman's loop or Butterfly loop.
Figure parts A–D show steps in forming a "short tie" Western Union splice. Figure parts E and F show two possible "long tie" variations. [2]

The Western Union splice or Lineman splice is a method of joining electrical cable, developed in the nineteenth century during the introduction of the telegraph and named for the Western Union telegraph company.[3][4] This method can be used where the cable may be subject to loading stress. The wrapping pattern design causes the join to tighten as the conductors pull against each other.[5]
