04 Scenic N/S/F ABS Sensor Replacement

Hi Guys, it would appear that my N/S/F ABS Sensor is faulty and needs to be replaced. I have checked the wiring and connections and these are all good and the diagnostics reports short or open circuit fault. When looking at the sensor it appears to be a push fit but I cannot see how to get the old one out. Has anyone changed one of these and if so, how do you remove the old one without damaging the clip that retains it in situ?



Any pointers or pictures would be a great help.
