A concrete element (1) for protecting an underwater installation, which element is shaped as an elongated, curved shell segment having two gable ends (2, 3), a bottom side (4) with a longitudinal cavity (5) for receiving the underwater installation, a top side (6) designed for low frictional resistance against a trawl, and at least two through-going apertures (7, 8) from the top side (6) to the cavity (5). The projection of the gable ends (2, 3) is inclined so that the top side (6) becomes longer than the bottom side (4), and the concrete element (1) is provided with, or prepared for attachment of, at least one connecting member, for interconnection with a corresponding connecting member of another concrete element. The connecting members are of a design such that the distance between the outer edges of the gable ends of two interconnected concrete elements becomes smaller than 30 centimetres. |
