An anchor removably positionable within a cavity in a substrate is disclosed. The anchor has an anchor body from which a plurality of resiliently biased legs extend. The legs are movable between a first position within the envelope of the anchor body diameter, and a second position extending radially beyond the anchor body diameter. The legs are biased to assume the second position when unconstrained. Free ends of the legs have engagement surfaces receivable within an insertion tool for constraining the legs into the first position. An attachment extends from the anchor body for connection to an item to be attached to the substrate. Insertion of the anchor into a distal portion of the cavity having a reduced diameter forces the legs into the first position, allowing engagement of the insertion tool with the legs and removal of the anchor from the cavity.
