A symmetric wedgelock system (18) includes a compression device (30) having a longitudinal axis; a plurality of segments arranged along the compression device including at least one drive segment at each end (38), (40) and at least one working segment in between each working segment including at least two sections having diverging sides forming a concave wedge facing an associated drive segment; each drive segment having converging sides forming a convex wedge (74) facing an associated working segment; the compression devi ce includes an adjustment device for applying a compressive force along the longitudinal axis to drive the convex wedges (84), (86) of the drive segment into the concave wedges (108), (110) of the working segment to drive apart laterally the sections of the working segment.
