Duckbill Clip Fitting



See Figures 1 and 2

  1. Special tools are available from Mazda and other manufacturers for removng retaining clips. Use Mazda Tools 49-UN01-053 and 49-UN01-054 or equivalent. If the tool is not on hand, go onto step 2. Align the slot on the push connector disconnect tool with either tab on the retaining clip. Pull the line from the connector.
  3. If the special clip tool is not available, use a pair of narrow 6-inch slip-jaw pliers with a jaw width of 0.2 in (5mm) or less. Align the jaws of the pliers with the openings of the fitting case and compress the part of the retaining clip that engages the case. Compressing the retaining clip will release the fitting, which may be pulled from the connector. Both sides of the clip must be compressed at the same time to disengage.
  5. Inspect the retaining clip, fitting end and connector. Replace the clip if any damage is apparent.
  7. Push the line into the steel connector until a click is heard, indicating the clip is in place. Pull on the line to check engagement.

Spring Lock Coupling


See Figures 2 and 3

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.
