That would depend on which disconnects you get, you can get ones with a screw thread that will take a barb fitting or a screw on JG fitting. You can also get them with just a barb.
I've just fitted out my 4 keg fridge with the barb type and they seal fine with no need for any jubilee clips or the like. Buying JG fittings is just more expense that you could otherwise spend on grain and hops.
