In metal pipe but are still 2 holes, which can use a screw to stabilize it by courageous assembly (= puncture of a plastic part). Since I have no experience, how long does that, but it seems to be working for now. Perhaps it is indeed the manufacturer nor the idea, because a metal Upgrade to sell.
As so often: a good product, which is of limited use by a single vulnerability.
