Abstract
A locking threaded connection (a) providing free relative rotation in a first direction, (b) preventing unintended relative rotation in a second opposite direction, and (c) enabling intended relative rotation in the second direction. The connection includes male and female threaded portions and a helical spring therebetween. The spring is sized and configured to interfit with the male and female threads. The spring enables relative rotation in the first direction, but prevents relative rotation in the second direction. If removability is desired, the spring is provided with an accessible tang, enabling the locking force of the spring to be released.
