One with gun interrupts seduction of Bond (8)
I believe the answer is:
ligature
'bond' is the definition.
(ligature is a kind of bond)
'one with gun interrupts seduction' is the wordplay.
'one with' becomes 'i' (I've seen this in other clues**).
'gun' becomes 'gat' (gat is a kind of gun).
'interrupts' indicates putting letters inside.
'seduction' becomes 'lure'.
'i'+'gat'='igat'
'igat' inserted within 'lure' is 'LIGATURE'.
'of' is the link.
(Other definitions for ligature that I've seen before include "Surgical, musical, tie" , "Cord used for tying" , "Bond" , "Musical slur" , "Character combining two letters" .)
