An improved anchor (A) for embedment in a concrete member (S) to provide a lifting attachement for the member. The anchor (A) comprises an elongate bar (10) having convergent (16a and 18a) and divergent surfaces (16b and 18b) wherein the divergent surfaces (16b and 18b) face outwardly to direct axial pull-out forces imparted to the bar divergently and laterally into a concrete member (S) within which the anchor (A) is embedded. Divergent wings (36) are fixed to and extend laterally from the bar (10) to direct lateral forces imparted to the bar (10) in divergent directions relative to the bar (10).
