Abstract: The invention is a wire-guide latching device 22 for a wire-harness assembly form board 24. The device 22 comprises a first post 26 having first and second ends, with the first end coupled to the board and the second end terminating in a circumferentially disposed laterally extending flange 30. A second post assembly 32 is provided having first and second ends, with its first end coupled to the board 24 and incorporating a rotatable arm 52. The arm is rotatable from a first position wherein the arm's free end is in overlapping relationship with the flange 30 of the first post 26 to a second position out of engagement therewith and, further, moveable to a third position in the opposite direction from the second position. A detent system 80 is provided which is adapted to selectably hold the arm 52 in either the first or third positions. A spring 60 is provided which is adapted to bias the arm 52 to the first position when it is moved toward or into the second position.
