The invention relates to a channel joining system (21) with a mounting channel (32) and two joining parts (22) for joining the mounting channel (32) to a support (16). The mounting channel (32) has an installation opening (36) that runs along the longitudinal extension of the mounting channel (32), that has a clear width (B) running perpendicular to the longitudinal extension and that, in one of the profile walls (34), has several fastening openings (37) that are at a distance from each other in the longitudinal extension of the mounting channel (32). The fastening openings (37) each have a clear length (L) running in the direction of the longitudinal extension of the mounting channel (32) and a clear width running perpendicular thereto. Each joining part (22) has a contact section (23), a holding section (24) and a fastening section (27). The fastening section (27; 47; 107) has an engaging section (28) that can be inserted into the mounting channel (32) and that can be rotated so as to engage behind the edges of the installation opening (36), the length of the engaging section (28) is greater than the clear width of the installation opening (36) but smaller than the clear length (L) of one of the installation openings (37), and the width (N) of the engaging section (28) is smaller than the clear width of the installation opening (36) and smaller than the clear width of a fastening opening (37).
