A mutual and multi-restrained fixing fender to be used in navigation consists of one element (1) of elongated tubular form, provided with a double series of first tubular housings (4, 4a) that develop according to chords belonging to planes that intersect the element (1) obliquely and at right angles, each housing being provided with a corresponding first slit (2, 2a) that develops over the whole length thereof, suitable to bring the same housing into communication with the cylindrical outer surface.
<??>Said first element also comprises a pair of second opposed tubular housings (5) and respective slits (5a) that develop according to longitudinal exes and a number of third opposed housings (6) and slits (6a) that are longitudinal and separated by equal distance from the preceding ones, adapted to mate with countershaped tubular projections (7) obtained at the ends of the fender. |
