He's safe (5)

I believe the answer is:

peter

I believe this is a double definition.

'he's' is the first definition.
(I've seen this before)

'safe' is the second definition.
(I've seen this in other clues)

(Other definitions for peter that I've seen before include "Dwindle away to nothing" , "Early Pope" , "One of the Apostles" , "Safe; saint" , "-- Sellers, comic actor" .)

I've seen this clue in the Evening Standard.
