In a test tube (P10) for taking blood samples by vacuum suction through a double-needle device having an external needle for insertion into the vein while the other needle is internal, coaxial with and opposed to the first and fitted with a protective sheath forming a slidable elastic cap, and able to perforate a diaphragm of the stopper (T10), said stopper has an external extension (T22), with axial cavity (T24), which projects from inside the test tube (P10) to end in the perforable diaphragm (T26) at the extremity of the extension (T22); said extension (T22) can be inserted into the recess of the internal needle of said sampling device, without the need for bayonet-type connection and disconnection. <IMAGE> |
