Didn't notice the plug and socket version at the bottom of that page. Yes, similar but not identical, as far as I can judge from pictures. Handy not having screw and unscrew the wires.
I have not personally used them, but these automotive/marine connectors seem to offer a potentially very neat solution, with waterproofing to IP67, given that only very occasional disconnection (annual) is required. They come in various unit sizes up to 6-way, each way being rated at 14A. Two 6-ways would meet the OP's present needs with capacity to spare. http://www.12voltplanet.co.uk/superseal-waterproof-connector-pair-6-way-1-5-series.html
... I wrap this part of mine with looming tape (a bit like PVC electrical tape except it doesn't go gooey and fall apart after a few years) and the result looks quite professional...
The plugs are slightly fiddly to assemble (but not to the extent of being a problem) and they feel good in use. Pete
