Abstract
A quick-connect coupling for opening a valve to allow discharge of a liquid. The coupling is particularly suited for discharging motor oil from the oil pan or oil filter of an internal combustion engine. The coupling includes at least one latching element which engages the valve in order to open it. The other end of the quick-connect coupling is preferably connected to a hose that leads, in turn, to an oil collection vessel.
