Simple waterproof cable box connector

Waterproof box to protect cable connector for using outdoor, it is very simple and easy to use.
My case is that I have some water sensors placed in the home garden. and they need to be change or fix the sensors every few months. Everytime I replace the sensor, I have to cut the wire and make it sealed with electrical tape, which take time and effort.
And this water resistant box make my job a lot simpler.
