Abstract: A connection assembly secured a running tool into a tubular casing hanger. The connection assembly includes a frusto-conical threaded section on a running tool and a nose section of cylindrical shape located below the threaded section. The casing hanger has a bore with at least one circumferential recess. A collet ring having internal threads is initially carried on the nose section. The collet ring lands in the recess when the running tool is moved into the casing hanger. Continued movement causes the collet ring to deflect outward. The collet ring has threads on its inner diameter that slide on the threads of the running tool to latch the members together. Slots in the collet ring enable the outward deflection to occur. A pin engages the collet ring to enable rotation of the running tool relative to the collet ring to unscrew the members from each other.

Abstract: A quick connect/quick disconnect coupling utilizes a retainer mounted between expanded ring portions of a tube. A sleeve is mounted over the retainer such that projecting leg portions from the retainer extend outwardly through openings in the sleeve. Upon assembly into a socket these outwardly projecting leg members engage a socket contact face to secure the coupling in the assembled position. To effect removal of the coupling the tube is displaced within the socket such that the retainer is displaced relative to the sleeve. As the retainer is displaced relative to the sleeve a compaction annulus portion of the sleeve acts to compress the projecting legs such that the tube with the attached retainer and sleeve may be removed from the socket to effect disconnection of the coupling.
