Does anyone recognize this wire connector/splice mechanism? The wire was very heavy, which makes me wonder if it was power line. But solid iron would be unusual for power. I am not certain that this is even electrical in nature, it was installed on some wire I saw in a creek bottom recently. The hole through it may have been used to hold the center piece while the threaded ends were tightened.

UPDATE: No firm ID, but the consensus is that it probably isn't electrical in nature. Thanks for the help!
