The invention relates to a connection element, in particular a thermal adhesive bonding boss, to be introduced into at least one component, in particular a hollow chamber component, in particular a plate-shaped hollow chamber component which has hollow chambers, under the effect of pressure and rotation, comprising a main part which comprises a thermoplastic synthetic material. The connection element has a longitudinal axis and is designed to rotate about the longitudinal axis, and the connection element has an upper face with a tool placement point and a lower face which faces away from the upper face, wherein the connection element has an expanding portion made of a thermally activatable expandable material on the main part on a circumferential surface extending between the upper face and the lower face.
