The post consists of a rectangular tube section (10). So that the post can bend over at any desired point in its longitudinal direction in the event that it is driven into, the invention provides that two mutually opposing side walls of the rectangular tube section be provided with a continuous V-shaped constriction (13, 14) in the longitudinal direction, and that the wall thickness of the constricted side walls be reduced in a groove-shaped manner in the longitudinal direction (17, 18, 19, 20, 21, 22), at the constricted edges (15, 16) and at the transition points between these constricted side walls and the adjoining plane side walls (11, 12). <IMAGE> |
