I needed a few of these and couldn't find them for sale so I made some myself. The picture shows the one original piece on the top and the two I made on the bottom. The original may be stronger but these are plenty strong as long as the support pole doesn't get kicked, knocked, pushed out of place to stress the piece. I would suggest adding a couple drops of silicone or adhesive between the bottom of the pole if it sits on a tile or laminate floor. That would help a bit to prevent the pole from getting pushed out of place.
