A connection device is suitable for connecting two tubes to one another, and optionally to a fluid tank for fluid transmission piping of an aircraft or a spacecraft Also disclosed are pipes incorporating said tubes and said device; and a method for manufacturing said device. The device includes an injection-molded tip that has at least one angled or inwardly curved area and is made of a composite material with a thermoplastic matrix reinforced by a reinforcement system including carbon fibers. The tip has a median longitudinal mold parting plane (P). The carbon fibers extend so as to be oriented along the tip, which incorporates mechanical and vibratory stiffening means which are integrally molded with the tip and lie in said parting plane or symmetrically relative to said plane in said at least one area and/or immediately near said area.
A connection device for fluid transmission piping of an aircraft or spacecraft, the connection device being suitable for connecting two tubes to one another, the connection device comprising an injection-molded tip that has at least one bent or curved zone and that is made from a composite material comprising a thermoplastic matrix reinforced by a reinforcing system comprising carbon fibers, the injection-molded tip having a median longitudinal mold parting plane, wherein said carbon fibers extend in an axial direction of the molded tip along the injection-molded tip, said injection-molded tip incorporating mechanical and vibrational stiffening means that are molded with the injection molded tip and with said composite material to be integral with the injection-molded tip and extend in said at least one bent or curved zone and/or in the immediate vicinity of that zone, said mechanical and vibrational stiffening means extending in said median longitudinal mold parting plane or symmetrically relative to that median longitudinal mold parting plane and comprising said carbon fibers.
