...The male end is a normal lighter type plug which you remove the end when using the mentioned female part. Then you insert, screw down a collar and presto, no unintentional unplugging. Very clean install, secure connection.
Your referring to the Engel Posi-Fit, as noted it is a very, very secure and reliable plug connection for Engel (and re-badge) models. Any Engel dealer should have them in stock or be able to order. The new ARB models feature a similar plug which is actually a Hella plug with an adapter for conventional 12V plug use.
