A retrofitable manual disconnect apparatus includes an output shaft engagement member (20) that couples to the output shaft (13) of a powered movable barrier operator (12), a movable barrier engagement member (14) that couples to a movable barrier (11), and a hand-operable engagement mechanism (40) that controls coupling between the above components. In one embodiment, the hand- operable engagement mechanism (40) includes a pivoting handle (44) that cooperates with a biasing member (43) to control the position of a movable pin (41). In particular, the movable pin (41) can be controllable inserted in or removed from a hole (24) in the output shaft engagement member (20) to facilitate an engaged and disengaged state, respectively.
