PVC door seal problem

[Rollerball]

The back door to my house has a black rubber seal around the inner edge - one side of it slots into a fine groove that runs around the inside of the door frame.

This seal no longer wants to stay in place at the base of the door frame, so letting in water if it rains too hard when the wind is blowing against the door - I can slot the seal back into the groove without a problem but it comes out much too easily.

I've been hunting around online but can't seem to find a suitable replacement strip that will fit, so am wondering if I can somehow glue the existing seal in place.

If so, what kind of glue could I use that would be suitable and is of course strong and waterproof?

Or can anyone recommend a good place to try and buy a suitable seal?

Edit: after a bit more hunting the closest I can find is the bottom middle one on this image:

R6809

The only differences between mine and R6809 is that R6809 has a longer main gap between the 'base' and the 'tongue' (R6809 is marked as 5.3mm while mine stops a bit shorter). The shorter 'tongue' to the right also doesn't have the additional right angle at the tip on mine.

I guess it'll do though?

Just stretch it a touch ,drop a dab of super glue in the bottom of the groove if you think you need it, and slot it back in
