Security feature — hair piece? (4)

Ross

I believe the answer is:

lock

(Other definitions for lock that I've seen before include "Fasten securely" , "Mechanism to keep closed, door say" , "Secure a piece of hair" , "part of 10 [CANAL]" , "Fastening device" .)

I've seen this clue in The Guardian.
