The disclosure relates to a device for confining pollution material floating on the surface of water to a given area for subsequent collection, storage or other disposition thereof. The device comprises a variable group of individual watertight floatable barrels rising above the water and affording a barrier against the escape of the pollution material from the area, together with universal joints connecting adjacent barrels of the group to one another and serving to allow the individual barrels to pitch and roll in accordance with the pitch and roll of the water upon which the barrels are floated and thus to maintain the barrier operative despite undue water movement.
