A sleeve is slidable on the pole between the hook collar and a fixed stop collar spaced below the hook collar. The sleeve has a like plurality of slots to engage the free end of a tent support strut. The other end of the strut is pivotably connected to a tent support arm and intermediate the ends of the arm. One end of the arm has a bar to engage the hook and the other end a guy securing rope. In use, the bar on the arm is placed on the hook and the free end of the strut is engaged in the sleeve slot. The tent pole is then erected with the top of the pole (i.e., the end adjacent the hooks) projecting through a ring secured to the canvas. The guy ropes are secured to the arm.
