Tent securer (5)
I believe the answer is:
stake
'tent securer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for stake that I've seen before include "that's used in punt" , "Post; money wagered" , "A wager or pointed pole" , "Share (in a business); post" , "Wager; post" .)
