Abstract
A slip for an expanding hanger or patch is disclosed. The slip is mounted over the hanger body and has an internal profile that nests within a mating profile on the exterior of the hanger. When a compressive force is applied to the hanger, it shrinks longitudinally and as a result the slip is cammed radially to the extent the inside diameter of the surrounding tubing permits. When the swage is advanced, the diameter of the hanger increases forcing the slip into preferably penetrating contact with the inside wall of the surrounding tubular.
