Sliding door for a vehicle

The door (41) has a guide rail, and a sliding carriage that is supported at the guide rail in a longitudinally displaceable manner. The sliding carriage is connected with a vehicle body e.g. C-column, by a multijoint. A centering (42) has an end that is turned away from the multijoint and connected with a body-sided counter bearing (48) in a detachable manner. A damper (63) is provided for damping the movement of the sliding door during connection of the centering to the counter-bearing. The damper has a bolt (65) with a contact surface for the centering.
