Grips securely in hair? (5)
I believe the answer is:
locks
I believe this clue is a double definition.
'grips securely' is the first definition.
(lock can mean to grip or grasp)
'hair?' is the second definition.
(locks can mean hair)
'in' acts as a link.
(Other definitions for locks that I've seen before include "Canal features" , "Clusters of hair" , "raising devices for sailors" , "Secures; person's hair" , "Fastens - hair" .)
