Framework.—For connecting together rods or tubes, particularly in aircraft framework, the rods or tubes are surrounded at the connecting points by sleeves having flat parallel faces arranged oppositely in two or more pairs, the tubes being bolted together with the flat faces directly in contact, as shown in Fig. 6, or the flat faces may serve as seatings for lugs C2, D2, as shown in Fig. 4. The sleeves are formed of magnesium, aluminium or steel, and have tapered ends to distribute the stress and are secured to the tubes either by shrinking on or by bolting. The bolts shown in Fig. 4 are surrounded by enlarged bushes A3. Wiring plates P may be secured beneath the lugs C2.
