Lifesaver’s pad housing female flock? (3,4)
I believe the answer is:
mae west
'lifesaver's' is the definition.
(I've seen this before)
'pad housing female flock?' is the wordplay.
'pad' becomes 'mat' (I've seen this in another clue).
'housing' is an insertion indicator.
'female flock?' becomes 'ewes' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'mat' placed around 'ewes' is 'MAE WEST'.
Can you help me to learn more?
(Other definitions for mae west that I've seen before include "Life jacket; film star" , "Source of innuendos" , "jacket found floating in the sea" , "embraced many men in the main" , "Ex-player" .)
