Rodeo accessory (5)
I believe the answer is:
lasso
'rodeo accessory' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for lasso that I've seen before include "Cowcatcher" , "Rope used for catching cattle" , "Rope with noose for catching animals" , "What cowboy uses" , "use one for catching cattle" .)
