A buoyancy device to be clamped around least one longitudinal element. The buoyancy device comprises an assembled clamping device which is to be fastened around the element, and at least one buoyancy member connected to the clamping device. The buoyancy member is divided longitudinally in at least two sections and is arranged around the element together with the clamping device. The buoyancy member is divided in at least two separate or jointly pivoted buoyancy segments which may be folded around the elements(s) and loosely enclose a part of this (these). The clamping device is divided in at least two separate, or hinged together, clamping segments, adapted to be folded around the element(s), preferably in a firm and prestressed manner. The buoyancy segments are mechanically interconnected by at least one of the clamping segments by means of radically extending, complementary designed parts of the buoyancy segment and the clamping device respectively; so that the clamping devices and the buoyancy devices are interconnected to an integrated buoyancy device, by means of at least one peripheral tension element which is slideably fastened at fastening points, farthest out on the radially extending parts of the clamping segments, without stressing the buoyancy members. |
