Abstract: An improved anchoring device for well tools including installing and actuating apparatus for providing visual indication at the ground surface verifying proper latching and locking of the device in a casing string. The anchoring device includes a tubular housing assembly, a packer cup assembly secured to the lower portion of the housing assembly, an expansion sleeve slidably disposed within the housing assembly for forcing latching dogs radially outwardly from the housing assembly to engage an annular recess in the casing string, a setting sleeve longitudinally slidably disposed within the housing assembly telescopically related to the expansion sleeve and a lock sleeve releasably secured to the setting sleeve and telescopically related to the expansion sleeve.
