Having fishy connections, they're often bent (4)
I believe the answer is:
rods
I'm afraid I can't even guess how this answer relates to the clue.
Can you help me to learn more?
(Other definitions for rods that I've seen before include "Those angling" , "Fishing sticks or canes" , "Batons" , "Thin sticks or staffs of office" , "Long slender bars" .)
