An elevator door hold-close device in combination with a moving vane elevator door coupler having first and second vanes pivotally connected by links to form a parallelogram pivotally movable between a first compressed uncoupled position and an expanded coupled position. A structural member is fixed to the elevator car and has a friction pad configured for retentive engagement with a friction pad on the vane assembly to hold the car door closed against manual operation when the elevator car is in flight.
