Abstract
A device for positioning a member, such as a guide tube, so as to face the perforations of a plate. The device comprises a remotely fitted attachment finger, using for this purpose e.g. a pole onto which is threaded the remainder of the device. A remotely controlled locking system makes it possible to fix the two parts, each incorporating at least one attachment member and which can be fixed in a perforation. These displacements of the device, following the fitting thereof, are also remotely controlled. The device can be applied, to the inspection of the tubes of a steam generator of a nuclear power station by means of an eddy current probe or sensor.
