ABSTRACT:
A quick connect-disconnect coupling comprises a coupler joined to a standardized adapter to provide for fluid flow between first and second conduits. Locking mechanism comprises a four bar linkage which minimizes the manual effort required to connect and disconnect the coupler from the adapter. An over the center relation of the four bar linkage locks the coupler in coupled relation to the adapter to minimize inadvertent decoupling.
