Hi there - was there today (as were a few others) and did see snaplinks (one of which was a wire gate) with a YELLOW (I think) extension on bolt at bottom of the wall in that area.
To be honest, rather than take them for 'safekeeping', we decided to leave them in, on the basis that we thought the owner would
be back soon (maybe today) to reclaim them. Sorry if that turns out to be the wrong decision!
Couldn't understand what they'd been used for, but that's by the by.
They were there as I left, at 3.30, but I can't vouch for later, so good luck!
