Noticed that the rear bumper is a bit flexy but didnt think anything major, had a look underneath and there are two clips that dont seem to be connected.

They pivot on the one screw at the base and I am unsure how these are connected to the bumper but from looking at it they look like they are meant to "clip" to the bumper and each of these clips has 2 screw holes that maybe go on the bumper bar, there is only one screw used on the clip so it spins.

Can anyone shed some light on how these are meant to be fitted and if I just need new clips or screws or whatever to get the bumper sturdy.

Tried to take some pictures to better explain what I am on about.
