Head cold in cranium, for example? (5)

I believe the answer is:

bonce

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

'head' is the definition.
(informal term for a person's head)

'cold in cranium for example?' is the wordplay.
'cold' becomes 'c' (eg on taps).
'in' is an insertion indicator.
'cranium for example?' becomes 'bone' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'c' inserted inside 'bone' is 'BONCE'.

Can you help me to learn more?

(Other definitions for bonce that I've seen before include "Noddle (slang)" , "Nut" , "Head (slang)" , "Human head (informal)" , "Head - noodle" .)

I've seen this clue in The Telegraph.
