A collapsible tubular rod includes a socket body having an inner friction surface adjacent to one end thereof, and a tubular rod body coupled to the socket body and having a plurality of rod segments configured to be end-to-end engageable such that the rod body is convertible from a collapsed state to an assembled state in which the rod segments are successively engaged with one another by pulling of a connecting cord led through the socket and rod bodies. A releasably clamping member has a radially expandable tubular plug mating with and axially movable relative to the inner friction surface so as to be displaced from a normal position for gripping the connecting cord to an expanded position for tension adjustment of the cord when an actuator is actuated manually to move axially or radially.
