I think I'm going for these
Don't. Apart from the fact they don't sound great, they only take very thin wire, are not very secure at all and break easily.
Use bare wire in them and it's easy for strands to go sideways and cause a short. You can tin the end of the wire, or solder a little copper rod to the end of thicker cable, but then the wire pulls out even easier.
But the main reason for avoiding them is that they're just crap! Very thin crappo plastic, tiny spring in there, one good tug the wrong way and they just snap. They're rubbish on the back of a hi-fi but no way I'd use them on a wall.
I'd mount a couple of XLR sockets to the wall with XLR plugs on the cable, something like that. The wall will break before they do.
