A wiring head housing, particularly adapted for use in an automatic cable harness forming machine, incorporates a uniquely mounted, resiliently locked and resettable guide tube assembly that allows a guide tube, while being moved horizontally in accordance with a programmed pattern along an X-Y coordinate plane, for example, to be tilted up to a predetermined maximum degree of inclination, upon hitting an obstruction, in any direction from the predetermined resiliently locked position, while remaining secured to the wiring head. The spring means for resiliently locking the guide tube assembly continuously engages a rotatable member thereof in such a way, and is of such a type, that it is expanded in response to the guide tube being tilted in any direction. Such spring expansion (or displacement) is optionally employed to actuate a machine turn-off switch positioned adjacent thereto.
