Examples:
It's cold, I know.
She's awesome, I know.
Are these comma splices? If not, what is the name of the I know clause?
Is there a name for the whole structure?

When you invert the normal order of the sentence
I know it's cold.
you need a comma to make the sense clear:
It's cold, I know.
So while these appear to be two independent clauses, the first is actually a relative clause with an omitted that. Here is how the sentence would read if we were to put the that back in.
I know that it's cold.
And if we were to invert that, we would have
That it's cold, I know.
But that sounds a little stilted to the modern ear, so we just say
It's cold, I know.
In those examples, I know is a ‘tail’, a feature of speech which reinforces what is being said.
