1. A clip for temporarily assembling at least two drilled structural parts, comprising:
a tubular main body extending along a longitudinal axis X and having a bearing face intended to come into contact with a first face of the structural parts,
a spreader, and
a clamp able to pass through aligned holes, made in said structural parts, the clamp being movable in translation along the longitudinal axis X, driven by rotation about said longitudinal axis X of a tie rod provided with a threaded bore cooperating with a threaded end of said clamp, the clamp including flexible branches each terminating in a hooking nose intended to come into contact with a rear face of the structural parts, said flexible branches defining a plurality of pairs of adjacent branches and being able to move radially and progressively along the spreader, which is placed between said flexible branches and fixed with respect to the main body, under an effect of a recoil of the clamp, wherein
the spreader includes a transverse end rotationally fixed in a locking groove provided in a fixed element with respect to the main body,
the clamp further includes one or more longitudinal grooves capable of sliding on said transverse end when the clamp moves relative to the main body and capable of blocking a rotation of said clamp relative to said transverse end,
each pair of adjacent branches of the clamp are separated by a respective one of a plurality of slots, and
at least one of the plurality of slots is aligned with and communicates with one of the one or more longitudinal grooves of the clamp and at least one slot of the plurality of slots is offset from all of the one or more longitudinal grooves of the clamp.
