Abstract
An internal tube is inserted into an external tube to align first bolt holes provided through opposed walls of the external tube with second bolt holes provided through opposed walls of the internal tube. A bolt is inserted through the first bolt holes and through the second bolt holes to connect the tubes together when the bolt holes are aligned. An error-proofing clip is mounted in the internal tube and has a tongue extending from the end thereof to reach into the external tube and block the insertion of the bolt through the first bolt holes of the external tube until the insertion of the internal tube has proceeded fully to bring the first bolt holes of the external tube and the second bolt holes of the internal tube into alignment with one another, thereby preventing a premature installation of the bolt through only the first bolt holes.
