If you look at the pictures, it shows a "3 pin 30 amp plug" but the description and the bottom picture describe (and show) a 4 pin 50 amp system. I'm not sure if this will fit your trailer connector, some are unique but most are universal. Anyway, this link may get you started. I don't believe the weather shield and the black ring are available as separate parts, I believe the smallest component available is the entire plug assembly.

ADDED: MARINCO does sell the individual ring, but I don't think Marinco parts are compatible with CAMCO or LCI components. https://www.amazon.com/Marinco-510R-...DE0RBWVWD&th=1

ADDED #2: Here are two other brand locking rings so apparently they are available as separate components ??? :

Ahhhhhhh Locking Ring! Thanks for the links, ordered the camco, hopefully works out
