'Fetters' in the Bible

because that he many times with fetters and chains had been bound, and pulled in pieces by him had been the chains, and the fetters broken in pieces, and none was able to tame him,

For he commanded the unclean spirit to come forth from the man, for many times it had caught him, and he was being bound with chains and fetters -- guarded, and breaking asunder the bonds he was driven by the demons to the deserts.
