ABSTRACT:
A coupler for connecting and disconnecting a first hydraulic connector and a second hydraulic connector. The coupler has a first end and a second end. The coupler first end has a threaded opening adapted to combine with a threaded connector. The coupler second end has an opening with several members movable relative to the longitudinal axis of the coupler. The movable members have a first position wherein they are moved outward to make the opening larger and a second position wherein they are moved inward to make the opening smaller. The opening in the coupler second end is adapted to receive a threaded connector when the movable members are in their first (larger) position. After a portion of the threaded connector is inserted into the opening, the members are moved to their second (smaller) position thereby securing the threaded connector to the coupler second end.
