The present invention relates to a device for blocking the needle (2) of auto-protected puncture systems, comprising a protector (3) having a groove (8) and an elastic flexible sleeve (4) which are mounted on a vacuum tube support (1), allowing automatic retraction of the needle (2) into the protection position. It consists of a short cap (15), mounted on the grooved protector (3), which can be moved in the anteroposterior direction, thus blocking any displacement of the needle (2) after use. <IMAGE> |
