ABSTRACT:
A connecting device for connecting first and second tubular pieces of an aircraft turbine engine may include a rigid ring with an at least approximately S-shaped cross section. The rigid ring is housed in a recess of an acoustic protection cellular core of the first tubular piece and includes: (1) an external branch, which bears against an external skin of the second tubular piece and is secured to the latter by a first fixing device; (2) a back, arranged facing an edge face of the cellular core; (3) a front arranged facing the first tubular piece, after the first and second tubular pieces have been connected; (4) a transverse branch connecting the back to the front; and (5) an internal branch connected to an internal skin of the second tubular piece and secured to the latter.
