Of note, the weedless system that you show in the picture is one of the first weedless hooks that was used in the US. Another US product that sold well especially in europe due to the different species that we target here, is the Stick Guard. Or, look for "Hook guard" on basspro.com.
I've used the system you show a bit, then the stick guards for years, however you can use a soft and thin 2 mm silicon tube. Those tubes are normally used or carp rigs I think, but they are fit for purpose for this sort of application. Easy to find in UK tackle shops and can adapt to a simple hook or treble.
