Locks in a stable, say (4)

Ross

I believe the answer is:

mane

(Other definitions for mane that I've seen before include "Animal's neck hair" , "(Lion's) hair on neck" , "Lion or horse's 10 Across" , "Name for hair on horse's neck" , "Neck hair of an animal" .)

I've seen this clue in The Wall Street Journal.
