ABSTRACT:
A coupling apparatus is provided for quick coupling of a plug container or the like to a casing collar. A body of the plug container is located above the casing collar. A main seal seals between the body and the casing collar. An adjusting assembly has a variable engagement with the body. An annular locking device is connected to the adjusting assembly for longitudinal movement therewith relative to the body. The locking device locks the body to the casing string. The locking device has a lower end movable between an open position wherein the casing collar can pass through a central opening thereof, and a closed position wherein a radially inward extending lip of the lower end of the locking device is located directly below the casing collar. The main seal is hydraulically biased against the casing collar. An initial compression of the main seal is provided by varying the threaded engagement of the adjusting assembly with the body so as to pull the lip of the lower end of the locking device into engagement with the casing collar and to thereby pull the main seal down against the casing collar.
