Rodeo prop (5)
I believe the answer is:
lasso
'rodeo prop' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lasso that I've seen before include "Rope with noose for catching animals" , "Rancher's rope" , "Long-noosed rope" , "Cow catcher" , "Ling-nosed rope" .)
