When you need a connector to get plugged, and stay plugged, there is one options - short of using a tube of liquid nails.
NC3FX-SPEC features a locking ring for the highest security of connection and uninterrupted RF-screening.
By twisting the ring once connection has been made, it locks the connector firmly into place. While it has the effect of making your connection quasi theft-proof, it also may prove useful for overly flamboyant singers, who like to windmill with their stage microphone.
