The invention provides apparatus for use in connection with the casting of bodies, e.g. of concrete panels, which are to contain within them one or more anchor members which extend towards the surface of the body and are accessible within recesses formed in said surface. The releasible attachment of a recess former to an anchor to form an assembly for use in the casting of a body in which body the anchor is to be secured during casting and from which body the recess former is to be removed after casting to leave a cast recess containing a portion of the anchor is provided in which a connector member is applied to the said portion of the anchor to engage at least one formation provided on said anchor, the connector member and the said portion of the anchor are placed into a cavity in the recess former, and the connector member is releasably secured in the cavity, the arrangement being such that the walls of the cavity bear on the connector member to prevent the disengagement thereof from the said formations on the anchor while the connector member is in the cavity in the recess former.
