Makeshift twist-tie (4,7)

I believe the answer is:

pipe cleaner

(Other definitions for pipe cleaner that I've seen before include "Smoker's accessory" , "Smoker might use such" , "one's wiry, for a smoker" , "Wire covered with tufts of wool" , "Smoker's aid" .)

I've seen this clue in The New York Times.
