An extraction device of a platform for holding a blade fitted with an upstream flange, out of a turbomachine rotor disc, and extraction method using the device. The device includes a handle fitted with a radial annular shoulder extended by a threaded pin, a proximal ring and a distal ring having a tube extended by a radial collar and a sleeve. The proximal ring is arranged around the pin, the tapped distal ring being screwed onto the other end of the pin and the sleeve being arranged around the two rings between their respective collars. Screwing of the handle results in moving the distal ring towards the proximal ring, radial deformation of the distal part of the sleeve against the flared part of the cylindrical orifice of the flange and its being joined to the latter. It is possible to conjointly extract the platform and the device from the disc.

An attachment system intended to equip a wall, the system including a nut intended to receive a screw of which the orientation is normal to the wall, the screw passing through an element such as an outer panel in order to attach the element to the wall. The attachment system comprises a socket having a threaded cylindrical outer face intended to be screwed into a hole passing through the wall and having dimensions greater than the dimensions of the fastener that the repair socket replaces, the socket carrying, in the central region of same, a nut receiving the screw.
