A device for handling and towing a submersible object includes a tilting structure with a support, to pivot about a first axis parallel to a horizontal plane, and equipped with a guide device, a pivot connection about a second axis in a plane substantially perpendicular to the first axis, to allow a rotary part of the tilting structure to rotate relative to the support, the rotary part having the guide device, a stabilizing device to keep the rotary part in a deployed position relative to the support provided a torque of the relative pivoting between the rotary part and support about the second axis does not exceed a predetermined threshold, to allow the rotary part, equipped with the guide device, to rotate relative to the support about the second axis once a torque of relative pivoting between the rotary part and support about the second exceeds the threshold.
