Abstract
A telescopic strut has an axially extending rod and a tube receiving the rod for varying the length of the strut along a longitudinal axis. The tube has first and second ends, the second end has a pin extending therethrough. A locking system is mounted on the tube first end for adjusting the position of the rod in the tube and fixing the length of the strut. A coupling element having a tubular sleeve with a threaded outer surface is mounted on an outer surface of the second end of the tube. The sleeve has two diametrically opposed slots receiving the pin and an adjustment element mounted on the sleeve outer surface for axial movement along the axis. The adjustment element has a surface contacting the pin to limit the movement of the pin in the slots.
