The pipe is for venting battery gasses to the outside I believe, to prevent build-up of flamable gasses in the boot (mainly hydrogen I suspect). Probably not needed as much with modern sealed batteries.

I've always assumed the small brown cable is there for similar reasons, to ground something (not sure what exactly) to prevent build-up of static electricity, which could of course ignite battery gasses.
