Zusammenfassung:	A compliant, integrated, fastening and sealing system located on either end of cladding or on a liner hanger. It features protrusions in opposed directions whose contact edges are preferably hardened. The protrusions penetrate the surrounding tubular on expansion of the smaller tubular. Seals are included adjacent the protrusions so that seals between adjacent protrusions get forced toward each other upon flexing of the projections that penetrate the surrounding tubular. The attachment configuration is particularly suited for use with fixed swages or variable swages with limited dimensional adjustability when precise ID of host casing or open hole is unknown.
