Punch a fragile thing (5)

Ross

I believe the answer is:

china

'fragile thing' is the definition.
(as in porcelain china)

'punch a' is the wordplay.
'punch' becomes 'chin' (slang term meaning to punch someone on the chin).
'chin'+'a'='CHINA'

(Other definitions for china that I've seen before include "Porcelain ware and country" , "set of porcelain" , "Delicate porcelain from Cathay?" , "Where one regularly unloads junk" , "Fine earthenware" .)

I've seen this clue in The Times.
