That is, the fixing portion 5 is fixed to the vertical pipe, and the connecting plate 6 extends downward from the fixing portion 5. Further, the contact portion 7 is connected to the lower end of the connecting plate 6, and the contact portion 7 is brought into contact with the side of the vertical pipe P below the fixed portion 5. The fixing portion 5 in FIGS. 1 to 3 has a wedge-shaped end, and shows the fixing portion 5 that is locked and connected to a locking ring body P1 that is fixed to the side surface of the vertical pipe P in advance. In addition, the fixing portion 5
A clamp metal as shown in FIG. 4 may be used at the end. The fixing portion 5 of the type shown in FIG. 4 can be fixed at an arbitrary position on the side surface of the vertical pipe P. The connecting plate 6 shown in the figure is formed by connecting a plate bent in a flat U-shape to the fixing portion 5 and the connecting plate 6 (see FIG. 1). On the other hand, the abutting portion 7 is provided with a flat, substantially arc-shaped metal fitting at an end portion to be fitted to the outer surface of the vertical pipe P, and is connected to the fixed portion 5 via the connecting plate 6.
A hook 4 is provided at the upper end of the connecting fixed body 1 to be locked to the safety net R. The illustrated hooks 4 are provided as a pair facing left and right. In addition, the hook 4 mounting position is shifted back and forth so as to be easily locked to the safety net R, and the tip of each hook 4 is bent substantially horizontally (see FIGS. 1 and 3). The hook 4 is locked to the edge rope R1 of the safety net R, and can also be locked to the eyelet of the safety net R.

The supporting rod 2 is connected so as to be swingable above the connecting fixed body 1 from a position horizontally connected to the connecting fixed body 1. A slide rod 3 slidably projecting from the tip of the support rod 2 is provided inside the support rod 2. The illustrated slide rod 3 is crimp-fixed by a fixing screw 2A provided at the tip of the support rod 2 so as to be freely adjustable in length.
Further, a hook 4 is provided at the upper end of the slide rod 3, and the edge rope R1 of the safety net R is locked to the hook 4. Similar to the hooks 4 provided on the connection fixing body 1, a pair of the illustrated hooks 4 are provided so as to face left and right, and the tips of the hooks 4 are bent substantially horizontally. Further, the bent front ends of the hooks 4 are expanded back and forth so that the edge rope R1 of the safety net R is more easily locked (see FIGS. 1 and 3). The base end of the support rod 2 is swingably connected to the connection plate 6.
