Duplicates collapse of titanic swindle (9,5)

Ross

I believe the answer is:

identical twins

I'm a little stuck... Click here to teach me more about this clue!

'duplicates' is the definition.
Although both the answer and definition are plural nouns, I don't see how one could define the other.

'collapse of titanic swindle' is the wordplay.
'collapse of' is an anagram indicator.
'titanic'+'swindle'='titanicswindle'
'titanicswindle' is an anagram of 'IDENTICAL TWINS'.

Can you help me to learn more?

(Another definition for identical twins that I've seen is " Certain siblings".)
