ABSTRACT:
An expansion element comprises a plurality of identical hook or spiral shaped members which are interleaved such that when one of the members is caused to move radially outward it cooperates with adjacent members to move them outward also. The outward movement may be initiated by a centrally located plug which may either rotate or move axially.
