Abstract

The piston rod comprises a hollow tube(1) with the appropriate end components such as a fixing eye or a piston fixed at either end. The end components have a collar (7) and a spigot (6) which is fitted into the tube end. The spigot has an annular groove (9). Once assembled, a series of equi-spaced circular indentations are formed in the tube wall which engage in the annular groove (9).
