The plastic fittings are "John Guest" type. If you go to a hydraulic supplier, they will have them, or a cheaper (and just as good) alternative. You need a tap adapter with 1/4" socket. Just screw the adapter onto a standard brass tap with male thread on the outlet, then push the red pipe into the !/4" socket. ou can mount the tap on your shed wall, and the hose pipe fits on the tap's hosetail.
