System case helmet lock

[obc]

Have lost 1 of my system case helmet locks. Not actually a lock but a metal bar that slips through the helmet D-ring and under the handles of the system cases. Can't remember where I purchased it from - does anyone know who supplies/manufactures this particular item.
Thanks

Whew...took a little digging to find the name of these, but here you go. Called the lidloc.
