The present invention relates to a method for joining at least one joint part (3), provided with a through-opening (4), to a hollow profile (1), the joint part (3) being pushed with its through-opening (4) onto the hollow profile (1) up to a joint point (2), and the hollow profile (1) being expanded at least at the joint point (2). In order to improve the durability of the connection between joint part (3) and hollow profile (1), an adhesive (11) is arranged between an inner side (6) of the joint part (3) and an outer side (5) of the hollow profile (1) before the expansion in such a way that the adhesive (11) adheres to the inner side (6) and to the outer side (5) in the region of the joint point (2) after the expansion.
