Does anyone know what the rings are for on a quick coupler? These are the
couplers to join hoses, they have two or three handles that you snap
inwards to connect the hoses. The rings are on the ends of the handles. My
best guess is that the rings are a way to pull the handles back out to
disconnect but I wonder if I am missing something. I have found that if the
handles are stuck too tight that the rings are very awkward to pull hard
on.

For what? Air, gas, fuel, water, all kinds of quick couplers for
everything from a garden hose (very low pressure water) to the hoses
used for refueling ships at sea (fairly high pressure heavy oil)!
More info?
