Spring Lock Coupling

Push Connect Fittings:

WHAT IS A SPRING LOCK COUPLING
The spring lock coupling is a fuel tube coupling held together by a garter spring inside a circular cage.

HOW IT WORKS TO SECURE THE FUEL LINES TOGETHER
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 a redundant locking feature, a horseshoe shaped retaining clip is incorporated to improve the retaining reliability of the spring lock coupling.
