Arena, attractive thing for opener (4-4)

I believe the answer is:

ring-pull

'opener' is the definition.
(means of opening a can)

'arena attractive thing' is the wordplay.
'arena' becomes 'ring' (I've seen this in another clue).
'attractive thing' becomes 'pull' (something which draws in or attracts people).
'ring'+'pull'='RING-PULL'

'for' acts as a link.

I've seen this clue in The Times.
