External support for restoring valvular competence to veins, to be implanted about a vein (V), along its length. It includes a posterior and an anterior arcuate frame shell, in an elongated material. The posterior frame shell (1) includes two branches (2, 3) of said elongated material penetratingly shaped for an easy insertion thereof behind the posterior wall of the vein (V), through two paths prepared by the surgeon. Each frame shell (1, 2) includes a respective traction side including longitudinal rectilinear side traction branch means (5, 5'; 5A, 5' A). The two frame shells (1, 2) are conformed to be juxtaposed to each other about the vein (V) by longitudinal sides thereof. The traction sides are intended to be engaged to the vein (V) by opposite valve intercommissural walls (iw2, iw2) by means of surgical sutures (s1, s2) or hook means to dilate the intercommissural diameter of the vein by traction, so as to absorb the slackening of an incompetent venous valve by extending its cusps (c1, c2).
