The present invention relates to a roll-over protection device for a motor vehicle, particularly for a convertible, comprising a roll bar ( 2 ). This roll bar is provided with an at least nearly U-shaped design having a transverse yoke ( 3 ) and lateral limbs ( 4 A, 4 B) while leaving a loading opening ( 11 ) unobstructed, and extending such that it essentially spans the width of the vehicle. The lateral limbs ( 4 A, 4 B) can be displaced along fixed guiding devices ( 6, 7 ) in order to transfer the roll bar ( 2 ) out of a lowered non-operational position and into a raised supporting position. To this end, a central retaining and activating device ( 12 ) for the roll bar ( 2 ), said device being controlled by an actuator ( 18 ), is provided and/or a device ( 17 ) that synchronizes the displacement of the limbs ( 4 A, 4 B) of the roll bar ( 2 ) along the guiding devices ( 6, 7 ) is provided.
