Coupler that's Easier to Lock than Bulldog Collar-Lok  


So what keeps someone from just cutting the two metal springs that attach to the collar and then sliding it back to release the coupler, in fact, from the design it looks like the only thing holding it in place is the collar and to remove it even with a lock installed at the handle is to cut those two springs with a bolt cutter and then slide it back.


Expert Reply:

You are correct, all someone would need to do is cut the metal rods you pointed out to be able to slide the sleeve back of the coupler. Because of that you might be more interested in a Demco Coupler # DM13203-95 which uses a much more concealed latch and lock mechanism that wouldn't be as easy to defeat.

For a pin lock for the Demco the part # e98888 would work really well too.
