A recess former assembly (200) for creating a recess surrounding a cast in situ lifting element (60) in a cast concrete pipe (1) having a cast outer surface, is disclosed. The assembly has a frame (180) having locating lugs (183) engageable with components (81) of a reinforcing cage (80) to be positioned within the mould (70). The engagement of the lugs with the reinforcing components locates the frame in a rest position spaced from the mould. A removable recess former (150) is releasably retained in the frame. A lifting element (60) is retained within the recess former and has an anchor portion (64) extending therefrom. A non-rigid interconnection (182, 182A, 190, 191) between the lugs and the frame biases the frame and recess former to be urged towards the mould into an operative casting position in which at least a portion of the recess former substantially abuts the mould.
