Fruit for nippers? (4,6)

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

'fruit' is the wordplay.
I cannot really see how this works, but
'fruit' could be 'apples' (I've seen this before) and 'apples' is present in the answer.
The remaining letters 'crab' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'for' acts as a link.

Can you help me to learn more?
