Secured some junk, not Ted's (7)
I believe the answer is:
knotted
'secured' is the definition.
'some junk not ted's' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'KNOTTED' can be found hidden inside 'junk not teds'.
(Other definitions for knotted that I've seen before include "Entangled" , "Interlaced; gnarled" , "Twisted" , "one's impolitely asked to get" , "What to get when rudely addressed" .)
