PCT No. PCT/AU85/00183 Sec. 371 Date Apr. 1, 1986 Sec. 102(e) Date Apr. 1, 1986 PCT Filed Aug. 2, 1985 PCT Pub. No. WO86/01265 PCT Pub. Date Feb. 27, 1986.A joint for joining two elongate members transversely to each other, comprising a first member, second member, right angle bracket and threaded bolt. The bracket is fixed to the first member and projects from the end face which is to be accommodated within a complementary recess provided on the second member. A transverse hole is provided in the recess extending between opposite side faces of the member, and axially registers with a threaded hole in the end projection of the bracket and a groove in a longitudinal recess on the first member. The bolt clampingly engages the second member to the bracket with the bolt shank further engaging the surfaces of the hole, groove and the terminal end of a protrusion of the bracket. The projection and the recess operate to oppose rotational movement of the first member about its longitudinal axis relative to the second member.
