ABSTRACT:
A lockable telescopic joint is provided wherein two telescopic members may be fixed against telescoping action by tightening a glade nut, and yet after tightening there remains a substantial degree of rotational freedom so that one telescoping member may be rotated relative to the other by hand, and yet the members will not telescopically collapse short of applying considerably more compressive force than need be exerted to rotate the members.
