Claims (7)

1. A connecting device (1) for connecting between, on the one hand, a first vessel (2) having a neck (2a) blocked by a plug (3), and, on the other hand, a second vessel (4) including a male tip (4a) ), wherein said device includes a piercing element (5) for piercing a plug having, on the side opposite to the piercing tip (5a) of this piercing element, firstly, covering a tip (6) for tight connection with a male tip (4a) second vessel (4), and secondly, a filter a chamber (7), isolated from the external environment using a filter (8), two independent channels (9, 10) made in a piercing element (5) to ensure communication between the inner space of the first vessel (2) and correspondingly covering tip (6 ) and a filtration chamber (7) in a position where the piercing element (5) passes through the plug (3) while the present device also includes guide elements (11) for controlling the movement of the piercing element (5), formed at least sleeve (12) with in internal bore (12a), parts (13) securing the sleeve (12) on the neck (2a) of the first vessel (2) in the locked position, in which the internal bore (12a) is pressed against the tube (3) by its elements (14) to seal the inner bore (12a) with respect to the external environment, a plunger (15) on which the piercing element (5) is fixed and which moves under the influence of a simple pressing from the initial position, in which the piercing tip (5a) is located at a distance from the plug (3), piercing position in which the piercing tip (5 a) passes through the plug (3), characterized in that the device includes, in addition, restrictive elements (16) for the final locking of the plunger (15) in the piercing position, including a locking mechanism (17) on the plunger, and an additional element (18) for final locking on the sleeve, while the locking mechanism consists of a series of legs (17) evenly spaced around the axis of the plunger (15) and having elasticity to move from the center or to the center, and an additional stroke limiter, which is a ring second flange (18) on which the aforementioned stopper tabs (17).  2. The device according to claim 1, characterized in that between the plunger (15) and the sleeve (12) are elements (19) that prevent the rotation of the plunger.  3. The device according to claim 1, characterized in that the second vessel (4) is a syringe, and the enclosing tip is a cone (4A) of the lock type Lewer Lock.  4. The device according to claim 1, characterized in that the porosity of the filter (8) provides sterile filtration of any gas or liquid stream passing through it.  5. The device according to claim 1, characterized in that it includes a cap (21), put on the sleeve (12) and covering the covering tip (6) and made in such a way as to tightly close the part of the sleeve (12), opposite the tube (3).  6. The device according to claim 1, characterized in that it includes locking elements (22) for final fastening on the first vessel (2) by locking the parts (13) of fastening the sleeve on the neck (2a) of the vessel.  7. The device according to claim 1, characterized in that the female handpiece (6) has a filter (20) for filtering any liquid passing through it.
