Hit fellow in the band (6)
I believe the answer is:
swathe
'band' is the definition.
(thesaurus)
'hit fellow' is the wordplay.
'hit' becomes 'swat' (swatting is a kind of hitting**).
'fellow' becomes 'he' (I've seen this in other clues).
'swat'+'he'='SWATHE'
'in the' acts as a link.
(Other definitions for swathe that I've seen before include "Swaddle - cut strip" , "An enveloping bandage" , "Wrap in layers of, say, bandages" , "Row or path, of grass perhaps, when it is mown" , "Wrap; bandage" .)
