4 Pcs WBT-0144 Gold Plated RCA Plug Lock Soldering AudioVideo Plugs nnector,Black+gold,58mm2.28

These RCA plugs seem well made of good materials. The individual tines of the plugs are flexible enough to grip the chassis connector tightly, while allowing for slight variations in connector size. Tightening the locking collar holds them firmly in place, though probably not actually necessary. I much prefer these to other locking connectors I have used.
