Persons attached to cowboys? (5)
I believe the answer is:
chaps
'persons' is the definition.
(chap is a kind of person)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for chaps that I've seen before include "Blokes" , "Guy's" , "People" , "Men; leather trousers" , "Cowboy's trousers; men" .)
