Held out (8)
I believe the answer is:
'held out' is the definition.
('extend' can be a synonym of 'hold out')
This is all the clue.
(Other definitions for extended that I've seen before include "Stretched, drew out" , "Prolonged, lengthened" , "Elongated, expanded" , "Stretched out over time or space" , "Protracted, elongated" .)
