A connecting device for attaching to a rail of a scaffolding includes a barrel attached to a lever for coupling to a worker, two gripping members slidably attached onto the lever for adjustably engaging with the rails of different width, and one or more fasteners slidably attached to the lever for selectively engaging with the gripping members and for anchoring and securing the gripping members to the lever at the selected position, and for safely anchoring and retaining the worker on the scaffolding and for preventing the worker from falling from the scaffolding inadvertently. |
