A cylindrical reinforcing member `34 Vis welded or otherwise rmly secured within the inner member I I `and provides areinforcing means for the inner member II adjacent the locking plugs 32. The plugs 32 are slidable in registering openings 35 and 36 which are formed in the reinforcing member 34 and the inner member II respectively.

A lower plug 3l vis disposed in the lower endof` the inner member Il, being secured therein by a pair of diametrically disposed fastening meinbers 38. The plug 31 is formed at its lower end with an annular ange 39 engaging against `the lower end of the inner member II. A cushion member 40 engages about the lower end of the inner memberi I and includes a cylindrical side wall 4I having formed integral therewith a lower` wall 42 and vpreferably an annular rib 43 isformed at the lower end of the cushion member 40. The cushion member 40 may be made out of rubber or other cushioning material which `will not 20 without taking the arm gripping member 2,5 v
