If you wire up that clasp to 240v AC and place a small sign somewhere for H&S stating that you may get electrocuted due to building works
When I was a biker I knew somebody who dug a 6ft deep pit in front of his garage where only he knew where to walk and ride. He had reached his tolerance level with his bikes getting nicked.
He then placed a sign up saying construction under way keep out with all the relevant documentation. He woke up one morning to find a tea leaf in a pit!
He resisted the temptation to, in his words, 'give him a kickin'.
I think he claimed he couldn't read and he was just delivering leaflets or the like.
Not sure what happened.
Just another option.
