Bend cable (4)

I believe the answer is:

flex

I believe this clue is a double definition.

'bend' is the first definition.
(I know that bend can be written as flex)

'cable' is the second definition.
(type of flexible electric cable)

(Other definitions for flex that I've seen before include "Electric power cord" , "Bend - electric cable" , "Supply contract" , "Bendable cord" , "Bend (muscle?)" .)

I've seen this clue in The Times and The Irish Times.
