FIELD: instrument engineering.
SUBSTANCE: invention concerns the device (20) designed to connect a part of the first container with a part of at least one second container or with another device containing at least one basic component (21, 22) and the end component (23) containing complementary connection means (12C, 21D, 21'D, 25, 28) interacting with one another to ensure relative shift of the specified end component against the basic element, with the end component locking position at the basic component. According to this invention, the device includes springy retraction means (27), which are different from the specified complementary connection means and which provide operation possibility between the basic component and the end component in order to bring the latter to the specified locking position. The invention allows to improve mechanical strength and air-tightness of the device.
EFFECT: enhancing the mechanical strength and air-tightness of the device.
