Temporary fastener installation tooling and associated installation set

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

• a tubular tool body extending along a second axis and including an axial end with a first opening, the first opening being configured to receive the axial end of the fastener body and to block rotation of the axial end of the fastener body;
• an actuating device received inside the tubular tool body, rotatable relative to the tubular tool body and defining an internal cavity and an axial end with a second opening, the second opening being configured to open into the internal cavity, to receive the actuating element of the fastener and to prevent rotation of the actuating element of the fastener;
• an annular pressure chamber formed in the tubular tool body around the first opening;
• at least one duct, positioned radially relative to the second axis, connecting the annular pressure chamber to the first opening;
• at least one blocking element that is movable in the at least one duct between a retracted position and a projecting position where the at least one blocking element projects into the first opening;
• and
• a first fluid inlet opening into the annular pressure chamber;
• wherein the installation tooling is configured so that a fluid inlet into the annular pressure chamber is able to move the at least one blocking element towards the protruding position.
