Abstract
An apparatus for locking a tool into an annular groove formed on the interior of a subterranean well includes a segmented lock ring expandable into the groove by axially shiftable tapered keys wedged between segments of the ring. A latch collet between the keys and an associated running tool transmits an axial force from the running tool to the keys for wedging the keys between the segments of the segmented locking rings. After a predetermined axial travel of the running tool, the latch collet springs into the latch position, releasing the running tool and holding the keys in wedged position between the segments of the locking ring.
