bed guard for adult bed, for co-sleeping with baby?

[foundintranslation]

do these exist???
Atm ds (5mo and on the small side) is in one of these (sorry page is in German only) and it actually works really well. However, the (plastic) bits that attach it to the adult bed are really not very secure and it's fairly easy, at least for an adult, to pull it away from the adult bed. ds is starting to roll over and I'm worried that he also might manage to pull it away eg by rolling against the bars, although I don't think his rolls are that strong yet. I would like to continue co-sleeping for a good while yet. Do such bed guards exist, or would the best solution be to have him between me and the wall? TIA for any advice. Won't be able to come back and check for at least a few hours.

Wouldn't an ordinary bed rail work? Ie. those designed for a child in their first "proper" bed?

We used the type bonym mentioned until ds went into his own bed at 20 months. Ours was by Tomy I think!

thanks.
Sorry for only getting back now!
Thought I'd read somewhere that those types are often not suitable for babies? [puzzled]
