Abstract: An osteosynthesis device comprising first and second rods, a threaded member, and a connector having two jaws adapted to clamp onto the first rod, the connector having a threaded face and a housing extending between the jaws and the threaded face and adapted to receive the second rod bearing against the jaws, the connector being arranged so that a force (T) applied by the threaded member co-operating with the threaded face, against the second rod received in the housing towards the jaws urges the jaws towards each other so as to clamp onto the first rod. The connector is made as a single piece.

Abstract: This relates to a helicopter in which the outlet nozzle from the turbine engine is provided with an exhaust pipe which mixes the combustion gases with fresh air and directs the mixture downward.
