Abstract
A fluid coupling having a first part removably threadably connected to a second part, wherein one of the parts has a latch arm resiliently deformable by engagement with the projections incident to threading and unthreading of the first part on the second part. The projections and the latch arm have cooperating first cam surfaces and cooperating second cam surfaces arranged to engage one another and cooperating to require the application of relatively small and large forces to affect threading and unthreading of the first part relative to the second part.
