1. Connection insert, which may be molded or embedded into a plastic component and which comprises the following features before molding or embedding into the plastic component: a. a cylindrical main body having a radially outer side as well as a first and a second axial end,b. at least one circumferential collar arranged at the radially outer side of the main body which has at least partly the largest outer diameter compared to the remaining main body and which is arranged spaced with respect to the first and the second axial end of the main body, andc. a radially protruding structure arranged at the radially outer side of the main body, wherein d. the collar comprises a sectionally changing diameter in a circumferential course, so that a plurality of radial valleys and elevations are arranged in the collar, and whereine. the cylindrical body comprises a central bore with a radially inner side at which a connection structure is provided, or the cylindrical body comprises at the first axial end a bolt like axial extension. 2. Connection insert according to claim 1, the radially protruding structure of which extends continuously and/or discontinuously in longitudinal direction of the main body, preferably parallel and/or inclined to the longitudinal axis of the main body. 3. Connection insert according to claim 2, the radially protruding structure of which consists of a knurling extending parallel to the longitudinal axis of the main body, which is arranged on one or both sides of the collar. 4. Connection insert according to claim 3, the knurling of which consists of radially protruding webs which are evenly spaced with respect to each other and that have a polygonal, rounded or curvilinear cross-section. 5. Connection insert according to claim 1, the collar of which is limited in axial direction of the main body by two side surfaces, which at least partially enclose each an angle of at most 90° with the longitudinal axis of the main body, especially an angle of <90°. 6. Connection insert according to claim 5, the at least one collar of which is arranged axially centrally and/or adjacent to the axial ends. 7. Connection insert according to claim 5, the collar or the plurality of collars of which have commonly an axial width of 10% to 60% of a total length of the main body, preferably 20% to 40%. 8. Connection insert according to claim 1, comprising a thread, a bayonet closure or a radial knurling at a radial inner side of the central bore. 9. Connection insert according to claim 1, the extension of which is offset from the main body in a stepped manner and/or comprises preferably a length in the range of 40% to 200% of a length of the main body. 10. Connection insert according to claim 1, the extension of which is a connection bolt having an outer thread or a locking contour or a plug connection contour. 11. Embedding method for a connection insert according to claim 1, comprising the following steps: a. plasticizing of material in an embedding portion of a formed plastic component,b. pressing in of the connection insert in axial direction into the embedding portion such that material of the plastic component is dammed up at the collar and at least partially flows over the collar so that the collar forms an axial security against extraction after curing of the material. 12. Embedding method according to claim 11, wherein the collar of the connection insert comprises radial valleys and elevations so that during the pressing-in the plasticized material in the radial valleys flows over the collar and is dammed up at the elevations. 13. Embedding method according to claim 11, wherein the plasticized material flows into an axial knurling adjacent to the collar so that thereby a security against rotation is realized after curing. 14. Embedding method according to claim 11, wherein the plasticized material flows over an axial side surface on both sides of the collar so that the plasticized material forms an acute-angled undercut as two-sided axial security against extraction after curing. 15. Molding method for a connection insert according to claim 1, comprising the following steps: a. positioning the connection insert in a mold, preferably injection mold,b. surrounding, preferably over-molding, the connection insert with a plasticized curable material, wherein the connection insert is molded into a component, andc. curing the surrounding, preferably over-molded, material, and demolding the component with connection insert from the mold, preferably injection mold. 16. Molding method according to claim 15, wherein the collar of the connection element comprises radial valleys and elevations so that during the surrounding, preferably over-molding, the plasticized material flows over the collar at the radial valleys and is dammed up at the elevations. 17. Molding method according to claim 15, wherein the plasticized material flows into an axial knurling adjacent to the collar so that thereby a security against rotation is created after curing. 18. Molding method according to claim 15, wherein the plasticized material at the collar flows over an axial side surface at both sides respectively so that the plasticized material forms an acute-angled undercut as two-sided axial security against extraction after curing. 19.
