A protector comprising an inner tube, a lid connected to an upper opening of the inner tube through a hinge, and an outer tube for holding the inner tube in an inner cavity part of the outer tube. A blood collecting needle to which a tube is connected is stored in the inner tube. The inner tube comprises an annular seat face which seats on the base end part of a hub formed integrally with the blood collecting needle when the blood collecting needle moves downward. An operation lever extending downward is installed at the side of the lid, and an end part of the operation lever is slightly projected outward. When the blood collecting needle is moved, the inner tube is pulled integrally with the tube by the annular seat face to be slid relative to the outer tube until the end part abuts on the lower end part of an operation hole. Then, the lid is closed and the blood collecting needle is stored in the inner tube.
