Meter is broken, coming outside to get plug (13)

I believe the answer is:

'plug' is the definition.
(plug can mean an advertisement or promotional item)

'meter is broken coming outside' is the wordplay.
'broken' indicates an anagram.
'coming' becomes 'advent' (advent is the arrival or coming of something).
'outside' is an insertion indicator.
'meter'+'is'='meteris'
'meteris' is an anagram of 'ertisem'.
'ertisem' going inside 'advent' is 'ADVERTISEMENT'.

'to get' is the link.

(Other definitions for advertisement that I've seen before include "Bill" , "Placard" , "Publicity announcement" , "trailer" , "Public promotion" .)

I've seen this clue in The Guardian.
