Fop's prop (4)
I believe the answer is:
cane
'fop's prop' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for cane that I've seen before include "Hollow jointed stem of, say, bamboo (4)" , "Slender stem of bamboo etc" , "Eg, rattan" , "Stem of palm" , "Slender support, for 32 across say" .)
