I need to hold/lock two flanges together in such a way that I can lock the mechanism preventing someone else from separating the flanges (with some form of a key).
I realize this isn't specifically a car maintenance question, but I figure this audience would be the best suited to pointing me in the right direction.
Unfortunately there are no holes in the flanges and I can not add any.
I suspect a tool or clamp must exist that would meet these needs but I can't seem to find anything, or more likely don't know what key words to use when searching.
Can anyone suggest tools or how to find such a device?
