1. A safety device (1) for containers (2) holding fluid under pressure, each container having at least a upper component (3) and a bottom component (3) to be engaged with each other and defining an inner volume adapted to receive said fluid under pressure, said safety device comprising: a closing system (4) defining a closed position in which said components (3) are engaged together in a fluid-tight manner, and an open position in which they can be mutually moved and separated,a vent member (5) defining a closed position and a venting position of said fluid under pressure inside the container (2),at least one junction mechanism (14) to operatively connect the venting member (5) to the closing system (4), wherein the junction mechanism (14) is able to lock the closing system (4) to the closed position only when the vent member (5) is in the closed position; wherein the closing system (4) comprises at least two sealing elements (6), adapted to mutually seal both upper and bottom components (3) of the container (2), and an operating arm (8) designed to mutually engage and join together two sealing elements (6); and wherein said sealing elements (6) have the shape of half a ring so that, when two sealing elements (6) are joined together at protuberances (6a) on said sealing elements (6), and said sealing elements (6) are mounted on a rib (3a) that surrounds externally the whole circumference of the upper component (3) they achieve a close position of the container (2). 2. The safety device (1) according to claim 1, wherein said upper and bottom components (3) are engaged together along a vertical direction (2a) perpendicular to a circumference defined by the sealing elements (6). 3. The safety device (1) according to claim 1, wherein said junction mechanism (14) is mounted in a perpendicular direction relative to a circumference defined by the sealing elements (6). 4. The safety device (1) according to claim 1, wherein said closing system (4) is of the quick-action shut type without an operator's need of using any tool to operate the closing system (4). 5. The safety device (1) according to claim 1, wherein said junction mechanism (14) comprises: a sleeve (15) mounted around a channel (13) on which the vent member (5) is mounted;at least one friction-fit means (16) positioned at the closing system (4),at least one tailpiece (17) permanently connected on one side to the sleeve (15) and to the friction-fit means (16) on the other side; wherein the friction-fit means (16) has a “C” shape to surround protuberances (6a) of the sealing elements (6) to keep them joined together in a locked position only when the vent member (5) is also in a closed position. 6. The safety device (1) according to claim 5, wherein said junction mechanism (14) prevents the operating arm (8) to achieve the opening of the closing system (4) when the venting member (5) is currently in a closed position. 7. The safety device (1) according to claim 5, wherein said friction-fit means (16) is substantially in contact with a flange (8c) to prevent the rotation of the operating arm (8) when the closing system (4) is in a closed position. 8. The safety device (1) according to claim 5, wherein said vent member (5) comprises an operating knob (11) whose clockwise rotation moves said vent member (5) in a closed position and make the sleeve (15) in contact with the container (2) to mechanically prevent the separation of the upper component (3) from the bottom component (3) of the container (2) and concurrently locks the closing system (4) to a closed position by lowering the junction mechanism (14) which comprises the friction-fit means (16) that locks together the sealing elements (6) and prevents the rotation of the operating arm (8) to unlock the closing system (4) to an open position. 9. The safety device (1) according to claim 8, wherein said operating knob (11) whose counter-rotation moves the venting member (5) upward to a venting position to unseal a hole (13a) by lifting a sealing disk (18a) to allow the pressure inside the container (2) to escape through an inner cylindrical cavity (10a) of a cylindrical duct (10) and enables an upper movement of the sleeve (15), an attached tailpiece (17) and an attached friction-fit means (16) to allow the closing system (4) to move to an open position by causing the unlocking of the sealing elements (6) by turning the operating arm (8), now rotatable. 10. The safety device (1) according to claim 1, wherein the operating arm (8) has a cylindrical part (8b) and comprises at least one flange (8c) in a shape of a ring having a central axis parallel to the main axis of the operating arm (8) and having an internal diameter greater than the diameter of the cylindrical part (8b); wherein the flange (8c) is in contact with an internal side of a friction-fit means (16) to disallow an unscrewing action of the operating arm (8); and wherein the cylindrical part (8b) has a frustoconical portion and a threaded portion at one of its ending side which is screwed inside a threaded pivoting part (8a), mounted between protuberances (6a) of one of the sealing element (6); and wherein said two sealing elements (6) are locked by being joined together whenever the cylindrical part (8a) is rotated and its threaded part is further inserted into the threaded pivoting part (8a) causing the frustoconical part on the cylindrical part (8b) to force fitting into a frustoconical part of the protuberances (6a) of a second sealing element (6). 11. The safety device (1) according to claim 1, wherein said junction mechanism (14) comprises a friction-fit means (16) and one tailpiece (17) for each operating arm (8) that the closing system (4) is provided with. 12.
