摘要： The invention relates to a connection element (10, 40, 60, 88) for an interlocking connection to at least one component, wherein the at least one component is held between the connection element (10, 40, 60, 88) and a securing element (30, 50, 70, 90, 102), and the connection element (10, 40, 60, 88) and the securing element (30, 50, 90, 102) enter into a friction welded connection, having a head (12, 42, 86) with a drive and a shaft (14, 44, 62), wherein the shaft (14, 44, 62) has at least two cutting structures (18) on its front side, wherein the cutting structures (18) have cutting edges (46) situated in a cutting plane, wherein the cutting plane borders the shaft (14, 44, 62), wherein the cutting structures (18) are also spaced apart in the circumferential direction and define a cutting diameter. The invention is characterized in that the shaft (14, 44, 62) also has a cross-section, which has a reduced extension between the cutting structures (18) relative to the cutting diameter, wherein the area of the reduced extension extends in the axial direction at least with the length of the cutting diameter from the cutting structures (18) in the direction of the head (12, 42, 86).
