Hi Craig,
Bummer! I’m sorry you had trouble with this. We haven’t seen this happen yet but I can see how the connection would be vulnerable in rough conditions.
The slip ring and connectors are all assembled in a specific order and can’t be removed from the aluminum parts, but we can get you a replacement/spare of that whole assembly. If you’d like to do that, can you shoot us an email at support@bluerobotics.com and we’ll figure that out.
In the meantime, I’d suggest possibly securing the 8m extension cable to the side of the spool with zip ties or something so that if someone trips on it it pulls on the whole spool and not just the connector.
