Abstract
A connecting arrangement comprises at least one connecting rod having at one or each end a connecting stud. The stud has a head portion at its free end an adjacent neck portion which leads into the head portion through an inclined shoulder. A spherical or part-spherical connecting member has one or a plurality of bores disposed on its surface and extending into the spherical or part-spherical member from its surface for receiving the connecting studs at the end of the connecting rods. One or a plurality of threaded bores each intersect a respective one of the stud receiving bores and locate a grub screw, the arrangement being such that as a said grub screw is screwed into its bore it engages said shoulder on the stud to draw said rod into said bore. Various means can be provided for preventing rotation of the connecting rods about their own axes.
