Abstract

An anchor ring assembly (10) for anchoring to a mandrel (12) comprises an annular housing (14) which defines a through bore (15) to permit mounting on a mandrel (12). A plurality of slips (16) are circumferentially arranged within the through bore (15) of the housing (14), and a plurality of activator members (28) extend from an external surface of the housing (14) to engage the slips (16), wherein the activator members (28) are adjustable relative to the housing to extend the slips (16) radially inwardly to engage and grip a mandrel (12).
