Abstract
An expandable anchor/seal is pushed up a ramp until making contact with the surrounding tubular as or after the anchor/seal contacts the same tubular. The setting sleeve is made from high yield steel that has a weakened leading end to reduce the force required to push the leading end and the anchor/seal and an outer surface treatment at a leading end that engages or penetrates the wall of the surrounding tubular. Preferably a plurality of fingers are formed with axially oriented slots starting from a leading end allowing fingers to flex as they ride up the ramp on the mandrel for setting the anchor/seal and locking that set with the setting sleeve exterior surface configuration that can abut or penetrate the surrounding tubular.
