wherein each of the first base and the second base includes:
an insertion part to be inserted inside the protective tube, the insertion part having a first diameter when viewed in a first cross-section perpendicular to a length direction of the protective tube; and
a cover part integrally formed with the insertion part as a single piece and having a second diameter greater than the first diameter in the first cross-section,
wherein the insertion part includes a protrusion that protrudes from an outer peripheral surface of the insertion part to have an O-ring shape, and
