How do I reattach outside temp sensor?

[Long Islander]

While washing my car, I noticed the outside temperature sensor has become dislodged. It looks like it should just snap in to the plastic ring from behind so that the wire from the sensor goes towards the back of the car, but there doesn't seem to be any way of snapping it in the "ring."   There are two notches on the ring at 12 o'clock and 6 o'clock but no corresponding notches on the sensor.  The ring is made of hard plastic so it's not like you can just push it into the ring so it stays on tightly.  Any ideas?

It just snaps back into place from the back side.

I tried that but there's nothing to snap into.  When you push it in the ring, the sensor just fits in loosely.

From the service manual.

 

Press temperature sensor -10- into the inlet grille.

 

So, if this is not working then you may have a damaged sensor or the holder in the bumper maybe damaged.

I hear a click when I press the sensor in from the back of the "ring" toward the front of the car, but it still wiggles a bit.  It's not solid.  Thanks for the tip.
