a shank which extends along a longitudinal central axis of the connecting element, wherein the shank is provided with ribs extending in a radial direction with respect to the shank and wherein the shank has, at least partially, a polylobular cross section,
wherein the periphery of the polylobular cross section is convexly curved along its entire length, and, as seen in the radial direction, has regions with a larger radius or smaller curvature and regions with a smaller radius or larger curvature,
further wherein an angular position of the regions with a smaller radius or larger curvature and of the regions with a larger radius or smaller curvature changes along the shank, as seen along the longitudinal central axis.
