Claim 0:
1. A fastener, for the temporary assembly of at least two previously drilled structures, said fastener comprising:
a hollow body, extending along a main axis, a first end of said body comprising a bearing surface substantially perpendicular to said main axis;
a plurality of elastic clips movable in relation to the body and extending substantially parallel to the main axis,, a first end of each elastic clip comprising a hooking spur, the said hooking spurs forming a projection relative to the bearing surface of the body;
a spacer extending along the main axis, with a first end of the said spacer forming a projection relative to the bearing surface of the body, the plurality of elastic clips being positioned around the said first end, a second end of said spacer positioned within the body;
a connecting element movable relative to the body and extending on the main axis within the body, a first end of the connecting element being secured to a second end of each elastic clip; and
an actuating member connected to a second end of the connecting element by a threading/tapping mechanism;, said fastener being characterized as such that:
the connecting element includes oppositely facing lateral openings substantially positioned in a transverse direction (Y) perpendicular to the main axis, the said lateral opening extending axially between a first and a second closed ends; and
the fastener also comprises a stop extending along the transverse direction and secured to the spacer, said stop being positioned in the lateral opening of the connecting element, so as to slide between the first and second axial ends of said lateral opening.
