A void former for use with a lifting anchor cast into a concrete component. The void former is of two piece construction comprising a flexible element and a separate body which is substantially rigid. The flexible element is engageable with the head of the lifting anchor and is maintained in position by a snap fit with the rigid body which also acts to maintain the shape of the void during casting. After casting the rigid body is removed from the flexible element to thereby permit the flexible element to be disengaged from the lifting anchor by manipulation. The void former is thereby removable after casting without destruction of the void former and is thereby suitable for repeated use.
