Narrative:
On push back from gate the tow bar disconnected from the tug and the aircraft started to roll and made a slow 90 degree tail-right turn as in a normal push. In the turn the first officer noticed out his side window that we were disconnected from the tug. The first officer informed the captain who slowly applied the brakes and brought the aircraft to a stop. Maintenance; who was out to deice the wings and do an ice check told the captain that the pin was not installed in the tow bar at the tug. Maintenance checked the nose wheel and tow bar which were fine. The ground crew got another tug. The push and start were completed normally and the flight departed. When the ground crew checked in with the flight deck to continue the push back we discussed what had taken place and why; and the safety issues involved! Suggest remedial training for tug crews.
