How lovers may stroll (3-2-3)

I believe the answer is:

arm-in-arm

(Other definitions for arm-in-arm that I've seen before include "Aggressive male" , "With limbs interlinked" , "Closely interlinked" , "Closely linked" , "Of people, linked together in friendly way" .)

I've seen this clue in the King Feature Syndicate.
