REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5, 6 and 7
Fig. Fig. 1: Some spring lock couplings use a retaining clip

The spring lock coupling is held together by a garter spring inside a circular cage. When the coupling is connected together, the flared end of the female fitting slips behind the garter spring inside the cage of the male fitting. The garter spring and cage then prevent the flared end of the female fitting from pulling out of the cage. As an additional locking feature, most vehicles have a horseshoe-shaped retaining clip that improves the retaining reliability of the spring lock coupling.
