Ashtek has std JR compatible connectors, as shown in Marc S Mig15 photo. I don't know if Ashtek's lockable connectors are compatible or not, I don't think so. It would be a waste of money anyway, since the lockable are more expensive and they wouldn't lock with the JR connector. They have "clips" for locking std connectors together.

I've bought both types, used them as needed. Todd stocks them.
