Can anyone identify this bit of kit...!!?

Hi all
We are just packing up for a long trip and found a small zip lock bag in the drawer under the main cabin seat with some black bits and velcro straps in it....assuming they came with the van. Anyone know what these are for? Our manual is all in French and as far as we can see, they don't get a mention anywhere!
Cheers!
