One of my sensors at the rear (centre drivers side) is on the blink, after doing an oil change I was having a go yesterday at removing it and I think the fact that I was born with only 2 hands is making it difficult

Am I correct in thinking that you have to pull open the two black tabs and pull the sensor towards the vehicle body at the same time?
Had a few goes with no success, always a bit nervous about applying too much pressure in case I break it....
