In a system for connecting two tubes (11, 12), the end (13) of the first tube (11) is telescopically received in the end (14) of the second tube (12). A hole (15) in the first tube (11) is aligned with a hole (17) in the second tube (12) while at the same time smaller holes (16, 18) in the tubes (11, 12) are aligned with each other. A fastener assembly (20) which includes a fastener having a head (21) and a threaded shaft (22) with an enlarged sleeve (23) positioned therebetween, is passed through the holes (15, 17). The threaded shaft (22) can pass through the smaller holes (16, 18), but the sleeve (23) is larger than the holes (16, 18) and cannot pass therethrough. When a nut (25) is tightened on the threaded shaft (22) a shoulder (24) formed by the sleeve (23) bears against the tube (11) to thereby connect the tubes (11, 12). |
