Long part of an explosive (4)

I believe the answer is:

fuse

(Other definitions for fuse that I've seen before include "circuit-breaker" , "Common electrical safety device in homes etc" , "Safeguard in electrical circuit" , "Coalesce, melt together" , "Unite by melting" .)

I've seen this clue in the Universal.
