<p>The device has an inner peripheral wall (2) extending between a lower annular edge and an upper annular edge, and an outer peripheral wall (3) extending between another lower annular edge (3a) and another upper annular edge. The latter upper annular edge of the outer wall is integrated to the former upper annular edge of the inner wall. Openings e.g. slots (15, 17, 25), are arranged in the outer wall and are adapted for retaining a given object. The walls are made of a synthetic material. The support device is made of synthetic materials such as elastomers e.g. AXSON(RTM:polyethylene polymer),and flexible resin.</p> |
