摘要

An anchor device (20) for engagement with a wall (29) of a bore (30), the device having a profile including two interconnected arms (22, 23) defining a gap (52) between free ends (34, 35) thereof to accommodate relative movement of the free ends resulting from deflection of the arms during insertion in the bore, wherein the arms are coupled via an intermediate section (24) which includes an inset portion (25), at which the profile is in use spaced from the bore wall, so as to define contact portions (27, 28) at either side thereof for contact with the wall and wherein the inset portion is located substantially diametrically opposite the gap.
