Abstract

Auxiliary lead-through device for a turbomachine, including two coaxial annular shell rings, respectively an inner and an outer one, between which there extend radial arms, through at least one of which auxiliaries (20) are led through. An auxiliary retention unit is housed inside the arm, on one wall, the arm includes an aperture that can be closed off by a cover that is attached and fixed to the arm. The retention unit includes at least one first member fixed to the internal surface of the arm and at least one second member fixed to the internal surface of the cover. The fixing of the cover to the arm causes the auxiliaries to be clamped and retained between the first and second members.
