1. A vascular anchoring device intended to be introduced into a blood vessel by a catheter and including braces that are expandable in the radial direction, characterized in that the anchoring device comprises a substantially hollow-cylindrical part (1) including axially extending braces (2) departing from an end side, and a locking member (3) coaxially guided within the hollow-cylindrical part (1) along a guide wire (4) of the catheter, that the locking member (3) carries at least one ramp surface (9) on its end facing the braces (2), which ramp surface causes the braces (2) to expand by an axial displacement relative to the braces (2), and at least one stop (10) cooperating with the hollow-cylindrical part (1) in the expanded position, and that the guide wire (4) carries a further stop (7) which cooperates with a counter stop surface (8) of the locking member (3), or a stop surface of the hollow-cylindrical part (1), upon displacement of the guide wire (4).
