A bridge positioned between two parts, such as a nozzle support pipe envelope and a heat shield liner, includes a central part with inversed curvature thus having two contact zones with the nozzle support pipe envelope. Furthermore, the bridge includes two lugs, one of which can be mounted to slide in the heat shield liner.

In a variable-section turbomachine nozzle, a plurality of flexible follower flaps are provided that are interposed between adjacent controlled flaps against which the follower flaps are held by fastener means, each follower flap comprising a plurality of independent transverse boxes mounted side by side in a support sheet, the boxes contacting one another via their longitudinal edges and being held in the support sheet via their lateral edges which are engaged in the longitudinal edges of the support sheet, which longitudinal edges define respective bearing zones for bearing against the adjacent controlled flaps.
