An installation tool () has a tool body () comprising a first opening capable of blocking the axial end of the body () of a fastener () and an actuating device (), rotatable relative to the tool body and comprising a second opening capable of blocking a fastener actuating element (). The tool includes a pressure chamber () in the tool body a duct () connecting the pressure chamber to the first opening (), a blocking element (), movable in the duct between a retracted position and a projecting position; and a fluid inlet () opening onto the pressure chamber. An inflow of fluid into the pressure chamber moves the blocking element () to the protruding position.

Temporary fastener installation tooling and associated installation set

A clip, for use with structural parts, includes a main tubular body extending along a longitudinal axis and having a bearing face intended contact a first face of the structural parts, a clamp able to pass through opposite perforations, in the parts, and being movable along the longitudinal axis, driven by the rotation of a tie rod having a tapped bore engaging a threaded end of the clamp, the clamp further including branches that are radially and progressively separable along a separator, placed between the branches and fixed relative to the main body, under the effect of the recoil of the clamp, the separator including a transverse part introduced into a longitudinal groove of the clip and rotationally blocked in a groove provided in an element that is fixed relative to the main body.

Circular pin clip with fixed spreader

Insertable clamp, for the temporary assembly of structural parts, including a main tubular body extending along a longitudinal axis X and a bearing surface intended to contact a first face of the structural parts, an elastic clip capable of passing through drilled aligned holes, produced in said parts, the clip being moveable along the longitudinal axis, rotatable about said axis of a driver nut provided with a tapped bore cooperating with a threaded end of said clip, the clip comprising two branches having hooking spurs for contacting with a last face of the structural parts, said branches transversally and progressively moving apart along a spreader, between said branches and fixed in relation to the main body, when exposed to the recoil of the clip, the clamp further includes a compression spring inside the body and holding the threaded end engaged in the tapped bore so the clip remains aligned with the longitudinal axis.

Insertable clamp with aligned clip

The invention relates to a fastener () for the temporary assembly of structures (), comprising: a tubular body, extending between a first end and a second end comprising at least two longitudinal tabs (); a hooking element, rotationally prevented and capable of sliding axially in the body, said fastening element comprising a tubular base and a plurality of elastic clips () connected to one end of said base, each clip comprising a hooking spur (); a driving device for the fastening element; and a spreader () fixed relative to the body, the plurality of elastic clips being positioned around said spreader. The tubular base () comprises two longitudinal grooves in an outer surface; and the fastener is configured so that each tab () of the body is capable of sliding axially in one of said grooves.

Fastener for the temporary assembly of structures

The present invention concerns a fastening socket () for assembling at least two previously drilled structures, said socket comprising a substantially cylindrical body () and an enlarged head (); said enlarged head comprising first mounting surfaces () suitable for being assembled to a first installation component and for preventing said first installation component from rotating about the main axis. The socket comprises a first substantially cylindrical recess () extending along the main axis from the first end, said first recess ending at a planar shoulder () substantially perpendicular to said main axis, the first recess and the planar shoulder being received inside the enlarged head, the first mounting surfaces () being formed by an inner surface of the first recess.

Fastening socket for assembling structures and associated attachment

The present invention concerns a fastener () for the temporary assembly of at least two previously drilled structures () comprising: The connecting element is traversed by a lateral opening () axially extended between two closed ends (); and the fastener also comprises a transverse stop () secured to the spacer, the said stop being capable of sliding between the axial ends of the said lateral opening.
