A telescoping rod assembly (10) including an outer tube section (12) and an inner tube section (14) that is slidable disposed inside the outer tube section. The tube sections are locked into position relative to each other by a packing washer (18) that is fitted around the inner tube section adjacent the open end of the outer tube and a locknut (16) that is fitted around a inner tube and is rotatably secured to the open end of the outer tube. The inner tube and the locknut are provided with complementary outer and inner non-circular surfaces so as to couple the two members together so that they rotate in unison. The locknut can be tightened down over the packing washer to secure the tube sections into position relative to each other by the simple act of either rotating the outer tube or the inner tube.
