Looped cross, ancient Egyptian symbol of life (4)
I believe the answer is:
ankh
I believe this clue is a double definition.
'looped cross' is the first definition.
(I've seen this in another clue)
'ancient egyptian symbol of life' is the second definition.
(I've seen this before)
(Other definitions for ankh that I've seen before include "Egyptian cross" , "Sign of life" , "Waylay" , "Egyptian hieroglyph representing life" , "Ansate cross" .)
