1. A turbomachine separator comprising a device for de-icing the turbomachine separator, and a distribution element, wherein the separator is formed by an inner ferrule and an outer ferrule, wherein the inner ferrule comprises a plurality of rings, and is fitted with a first mounting flange and a second mounting flange disposed separate from and axially aft of the first mounting flange, each mounting flange comprising a shoulder of one of the rings and a shoulder of an adjacent one of the rings, the de-icing device comprising: an internal air supply duct, adapted to inject air into the separator, wherein said internal supply duct is connected to an air inlet, wherein the air inlet forms a projection external to the de-icing device, allowing a flexible connection with a tube of the distribution element for conveying hot air,a first mounting plate, constructed and arranged to be attached to the first mounting flange at an outlet end of the de-icing device;second mounting plate, separate from the first mounting plate and constructed and arranged to be attached to the second mounting flange; andan outer wall, configured and arranged to, when the first and second mounting plates are attached to the respective first and second mounting flanges, engage an inner surface of the outer ferrule. 2. The separator according to claim 1, wherein the flexible connection is produced by fitting an air conveyance tube into the inlet of the de-icing device. 3. The separator according to claim 1, wherein the flexible connection is produced by a seal positioned in the air inlet such that the tube is fitted and held directly in the seal. 4. The separator according to claim 1, wherein the device forms a bridge clamp enabling a tube of diameter smaller than the diameter of the air inlet to be inserted. 5. The separator according to claim 1, including an air inlet connected to the inner air supply duct, wherein the air inlet can be connected to means to draw air from a compressor of the turbomachine. 6. The separator according to claim 1, wherein the de-icing device comprises an upper outer wall disposed such that the outer ferrule can be attached and supported on the upper outer wall and has two apertures, wherein each aperture is able to accept a captive nut. 7. The separator according to claim 1, including multiple de-icing devices positioned between two flanges at different circumferential positions, so as to convey air into the nozzle through different air inlets. 8. The separator according to claim 7, comprising a circumferential distribution element including multiple air outlets, enabling multiple de-icing devices to be supplied with air, and including multiple inlets to connect multiple air conveyance tubes. 9. The separator according to claim 8, wherein the distribution element is a circumferential tube encircling a ring of the stator close to one end of the secondary flange. 10. The separator according to claim 8, wherein each conveyance tube is of roughly identical length. 11. The separator according to claim 1, wherein the separator includes an outer ferrule formed by a plurality of panels, wherein at least a proportion of these panels is assembled with one another through the de-icing device. 12. A turbomachine including a separator according to claim 1.
