The tool includes a bearing member (), a traction assembly () of the object (), movably mounted in a first direction relative to the bearing member (). It includes a plurality of hooking members (), mounted radially mobile relative to the traction assembly () between a contracted configuration and a deployed configuration. The tool comprises means () for keeping each hooking member () in its deployed configuration. It includes unlocking means () that include an elastic stressing member () applied on the holding means (). The elastic stressing member () is capable of being compressed to cause the unlocking of the holding means () and the passage of the hooking members () from their deployed configuration to their contracted configuration.

Tension meter () for measuring a mechanical tension (F) along a longitudinal direction (L) between a first element () and a second element () deployed in a well containing a fluid () having a fluid pressure, the tension meter comprising:&#x2014;a bar () comprising a first portion (), a second portion (), and a measurement portion (), and&#x2014;a hollow member () defining a first chamber () surrounding the measurement portion, the bar being free to expand within the hollow member under the mechanical tension (F) to be measured. The measurement portion includes at least one strain gauge (). The tension meter includes first sealing elements for keeping the first chamber at a first chamber pressure, the measurement portion being subject to a compression force (F) due to a difference between the fluid pressure and the first chamber pressure. The tension meter includes means for converting the fluid pressure into a traction force (F) applied on the second portion (), wherein the compression force (F) and the traction force (F) compensate.

The invention relates to a safety device for an oil well and to the associated safety installation. The inventive device comprises a valve housing () which defines a fluid flow passage (). The aforementioned housing () comprises a valve () which is used to seal the passage and which can move between an open position and a closed position and means for permanently biasing the valve towards the closed position thereof. The housing () also comprises releasable means () for connecting same to a working line with tubing that is intended to move the housing () in the conduit. In addition, the device comprises retractable means () for supporting the valve () in the open position and hydraulic means () for actuating the support means () in order to activate same upon reception of a valve open control signal. The aforementioned support means () and actuation means () are solidly connected to the housing () such that they can be moved simultaneously under the control of the line.
