<p>The invention relates to a recoverable anchoring device comprising: an anchoring sheath; an inserted bolt that protrudes from the distal end of the sheath; and a part for adjusting the longitudinal position of the bolt, the distal zone of the bolt including a zone of greater diameter, such that an interference zone is defined. The device also includes separation means which are used to separate the flared portion from the hole for the extraction of the device and which are inserted between the flared portion and the surface containing the hole, the outside diameter of the sheath being smaller than that of the flared portion, from the flared portion to the distal end.</p> |
