I had the same thought as Lin when I first saw it, but the leaves aren't right for any I've ever seen. The leaves on Antigonon leptopus are heart shaped with a sort of bumpy texture. The pink on the Coral Vine is a bract much like on Bougainvilla and I can't tell in the photo if it's a bract or not. The closeup almost looks like a Crepe Myrtle, but obviously it's not that. The pods look really close to Coral Vine. For me, the leaves say it's not Coral Vine.
