Balcony irrigation hub plug

Spare part for the holyday irrigation system which I use as a balcony irrigation system. Plugs into the irrigation pipe hubs, print in TPU, the spikes to be covered are in a cone shape, so the plug has to bend a little in order to get a tight grip. The irrigation system I use is from a commonly known german supermarket, there are equivalents from Gardena and the other major german supermarket which all 3 should be compatible with each other. There is also a garden hose adapter and its counterpart I use to automatically refill the container with in my other models
