Breaks in and bangs on the head? (9)

I believe the answer is:

infringes

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

'breaks' is the definition.
(infringing is a kind of breaking)

'in and bangs on the head?' is the wordplay.
'and' means one lot of letters go next to another.
'bangs on the head?' becomes 'fringes' (I can't explain this - if you can you should give a lot more credence to this answer).
'in'+'fringes'='INFRINGES'

Can you help me to learn more?

(Another definition for infringes that I've seen is " Breaks".)

I've seen this clue in The Globe and Mail.
