PURPOSE: To facilitate the manufacture, assembly, disassembly, and inspection by a joint having a visible joint member. CONSTITUTION: This joint 10 is integrally connecting a first tube 12 to a second tube 14, the first tube has a mount 20 at a predetermined distance from its end 18, and the second tube 14 has a return bend on its end 36. The second tube 14 telescopically fits over the first tube 12. Locking tabs 30 are engaged with cam to allow the return bend 36 of the second tube 14 to pass the locking tabs 30, The tabs 30 return to their rest inclination after the return bend 36 passes, to trap the return bend 36 between the locking tabs 30 and the mount 20, thereby locking the first tube 12 and the second tube 14 together, and providing a visible connection. |
