Abstract
The invention relates to a connecting element for pressing into or embedding in a component, having 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, is arranged between a circumscribed circle and an inscribed circle, and, as seen in the radial direction, has regions with a larger radius and regions with a smaller radius, wherein an angular position of the regions with a smaller radius and of the regions with a larger radius changes along the shank, as seen along the longitudinal central axis.
