A quiet fellow has protective gear (5)
I believe the answer is:
apron
'protective gear' is the definition.
'a quiet fellow' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'fellow' becomes 'ron' (masculine given name).
'a'+'p'+'ron'='APRON'
'has' is the link.
(Other definitions for apron that I've seen before include "Cook's garment" , "Protective kitchen wear" , "Aircraft parking area" , "Paved surface where aircraft stand when not in use" , "stage perhaps" .)
