Anti-rotation locking device for preventing separation of coupling nuts from fluid lines
First Claim
1. A device for preventing first and second joined parts from separating, comprising a resilient U-shaped member, a first arm of the member terminating in a shaped portion with an aperture formed therein defining an apertured end portion, a surface being coined along the internal surface of said aperture to engage a corresponding surface formed on said first joined part, a second arm of said member terminating in a shaped portion with an aperture formed therein defining an apertured end portion, a surface being coined along the internal surface of said aperture in said second arm to engage a corresponding surface formed on said second joined part, said apertured end portion in said first arm member being substantially coaligned with said apertured end portion in said second arm member, the apertured end portions being shaped to engage the joined parts such that the joined parts will not rotate relative to each other.

Abstract
A spring clip having two apertured end portions. In the preferred embodiment, the first end portion has an unidirectional clutch formed into the aperture wall, or face. The second end portion provides an aperture wall formed to provide an anti-rotation feature. In one embodiment, the clip is used with fluid adapters, the second end portion face having a serration and shape which raises the serration above the parent material to mate with the serration in the upper portion of the adapter lockring. The second end portion has different shapes depending upon the spring clip application.

10. A fluid connector and lock combination for connecting a tube to a base element that includes a fitting that is threaded into a parent material and includes a passageway for passing fluid, the combination comprising:
-
a lockring having external serrations that engages the parent material and the fitting through mutual serrations to fix the fitting relative to the parent material; a B-nut that circumferentially mounts the tube to the fitting through threaded engagement with the fitting; and a U-shaped spring member, a first arm of the spring member terminating in a shaped portion with an aperture formed therein, a uni-directional clutch being coined in the aperture surface, a second arm of said spring member terminating in a shaped portion having an aperture formed therein, the surface thereof being serrated, the serrations of said U-shaped member engaging the external serrations formed on said locking, said unidirectional clutch coacting with said B-nut.
