The 'hands' part of the helping hands will start with a threaded banana jack attached to the end of the nozzle on the Loc-Line hose.  This allows a large amount of flexibility in the attachments that can be put on the arms.

These are the basic alligator clips that go on the banana jacks.  I took a pair of pliers and bent the teeth of the top one inwards so that they don't bite into soft things like wire insulation.
