Temporary fastener installation tooling and associated installation set

An installation tooling for assembling a fastener to at least two pre-drilled structures, said fastener comprising:

• a fastener body extending along a first axis;
• and an actuating element projecting from an axial end of the fastener body, the actuating element being rotatable relative to the fastener body;
• the installation tooling including:
• a tubular tool body extending along a second axis;
• an axial end of the tool body comprising a first opening capable of receiving and blocking the rotation of the axial end of the fastener body;
• an actuating device, received inside the tool body and rotatable relative to said tool body, the actuating device defining an internal cavity, an axial end of the actuating device comprising a second opening onto the internal cavity, the second opening being capable of receiving and blocking the rotation of the actuating element of the fastener;
• the installation tooling being characterized in that it further comprises:
• an annular pressure chamber formed in the tool body around the first opening;
• at least one duct, positioned radially relative to the second axis and connecting the pressure chamber to the first opening;
• at least one blocking element, movable in the at least one duct between a retracted position and a position projecting into the first opening;
• and
• a first fluid inlet opening onto the pressure chamber;
• the installation tooling being configured so that a fluid inlet into the pressure chamber is able to move the at least one blocking element towards the protruding position.
