Sort of scarf for snake (3)

I believe the answer is:

boa

I believe this clue is a double definition.

'sort of scarf' is the first definition.

'snake' is the second definition.
(boa is a kind of snake)

'for' is the link.

(Other definitions for boa that I've seen before include "Large constricting snake" , "feathers around the neck?" , "Feathered neckwear - snake" , "Python" , "Wrap" .)

I've seen this clue in The Times.
