After having to replace all 5 of my Irrigreen heads at least once I learned there are two issues, digging up the connectors up to 3 ft away and fishing the new connections through, and trying to remove the head from the flexi pipe because the wire twists up around the head. I designed this simple quick sock for the head that holds the connectors close to the head. So when you have to replace the head, you unplug the connectors and can quickly unscrew the head from the pipe and screw the new one on and the connectors are right there. 

The device slides on where the cable holes are opposite the cut out at the base of the head. then wrap the wire clockwise around the base and the splitter will line up with the flat side opposite of the connectors and the connectors will slide right in. They are held in by the cable clips.
