ABSTRACT:
A first annular ring (44) has a keyed opening (64) sized to fit around the nut region (40) of a male coupling (14), and a second annular ring (42) has a keyed opening (52) sized to fit around the nut (26) of a female coupling (12). Each ring (42, 44) has mating ratchet teeth (56, 62), and these rings (42, 44) are biased together, thereby engaging these teeth (56, 62) and preventing rotation of these rings. This in turn prevents the rotation of the male nut region (40) with respect to the female nut (26). For tube-to-bulkhead locking, one facet (70) of one ring (44) is notched, and a pin (88) is pressed into an opening (84, 86) in the bulkhead (80). This pin (88) is sized to fit within one of the notches (74) in the ring (44), thereby preventing rotation of this ring (44) with respect to the bulkhead (80 ).
