PROBLEM TO BE SOLVED: To enable versatile connection of a bridging element with the overall height of the bridging element hole of a fastening element reduced, by improving the bridging element and a set composed of the fastening element and the bridging element.SOLUTION: At least the outside bridging element fork tooth (4) has an outside contact portion (9) extending in a planar shape in the extending direction (Z) and the bridging direction (Y) turning toward the adjacent bridging element fork tooth (4), and an inside contact portion (6) coming out perpendicularly to the bridging direction (Y) from the outside contact portion (9), and the outside contact portion (9) and the inside contact portion (6) form an outline having an L-shaped cross section. In this case, a mutual distance between the inside contact portions (6) of both outside bridging element fork teeth (4) is smaller than the mutual distance between the free ends of the outside contact portions (9) of both outside bridging element fork teeth (4). |
