Smoker on the tube (4)

Ross

I believe the answer is:

pipe

I believe this clue is a double definition.

'smoker' is the first definition.

'the tube' is the second definition.
(pipes are tubular)

'on' acts as a link.

(Other definitions for pipe that I've seen before include "Tube for conveying gas or liquid" , "Whistle" , "Wine cask; sing shrilly" , "Smoker's item" , "Transmit through a tube" .)

I've seen this clue in The Mirror.
