Disclosed is a surgical clip for end-to-end or end-to-side vascular anastomosis and for suturing blood conduits, which comprises a V-shaped base from which at least two branches project in a direction opposed to an apex of the V-shaped base. The branches each have a hook pointing toward the base, the branches are parallel to one another before plastic deformation and each branch forms with the corresponding hook a re-entrant corner with an apex angle of between 30° and 80°. The clip has three zones of preferential deformation, at an the apex of the V-shaped base and at connecting zones between the base and the branches. After plastic deformation, the two branches remain substantially parallel. The deformation of the clip has been concentrated on the apex of the base, the angle of which has narrowed under the stress of the gripper, and on the apices, which have opened.
