1. A coupling system for coupling units on a substantially rectangular load carrier, the load carrier having four corners, the coupling system comprising:
a column having a longitudinal axis, a rectangular profile, and four column side faces;
an anchoring piece having a longitudinal axis, a rectangular cross section, and four anchoring piece side faces, wherein the anchoring piece is configured for arrangement on one of the corners of the load carrier,
wherein the anchoring piece and the column are configured for mutual sliding engagement along the longitudinal axes thereof such that one of the anchoring piece and the column forms an exterior telescoping piece and the other of the anchoring piece and the column forms an interior telescoping piece, and wherein a first anchoring piece side face has either at least one cam or at least one opening and a first column side face has the other of the at least one cam or at least one opening, and the first anchoring piece side face and the first column side face are configured for locking engagement, the at least one opening and the at least one cam having mutually adapted locations and configurations such that the at least one opening and the at least one cam engage when the column and the anchoring piece are slidingly engaged, wherein the at least one cam comprises a semi-cutout punching having two bent faces that project or extend radially inward and meet at a ridge, wherein the two bent faces are partly strain-hardened to form an inflexible part, and wherein the punching has a cutout opening formed at an end of the two bent faces.
