The truss part comprises a tube component (11) and is connected to a further truss part via the intermediary of a manually releasable screw thread connection (14). The screw thread connection consists of a connecting bush (50), which via the intermediary of a second manually releasable screw thread connection (51,52) is connectable with the tube component. The screw thread connection comprises an inner screw thread in the outer end of the tube component and an outer screw thread on the connecting bush. Both screw thread connections rotate in opposite directions.
