A quick-connector comprises a first body portion, a second body portion, and a ball valve. The first body portion defines a first fluid channel. The second body portion defines a second fluid channel. The second body portion is coupled to the first body portion such that the first fluid channel is aligned with the second fluid channel. The first fluid channel and the second fluid channel form a fluid channel extending through the quick-connector. The ball valve is positioned in the fluid channel extending through the quick-connector. Movement of the first body portion and the second body portion relative to each other causes the ball valve to move between a flow position and a sealed position. In the flow position, the ball valve allows fluid to flow through the quick-connector. In the sealed position, the ball valve prevents fluid from flowing through the quick-connector.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, aseptic disconnection functionality that can substantially limit fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be functionally reconnected to each other after being disconnected from each other.

A fluid coupling has two similar coupling halves, each with a rotary body of a valve. A drive device for closing/opening the valve is associated with each rotary body. Each half has a coupling means for connecting/decoupling the halves by relative rotation. Securing means secure the connection when at least one valve is open and close the two rotary valves to disconnect/connect the halves. The drive device is arranged on one half and has a drive shaft which is associated with a valve shaft of the rotary body of the other half. A locking connection is configured which, when the halves are connected, connects the drive shaft on one half to the valve shaft on the other in a non-rotatable/releasable manner such that the rotation of the rotary body is controllable and relative rotation of the halves is blocked but the relative rotation when the valves are closed is permitted.

The invention relates to a locking coupling including a first coupling unit and a second coupling unit, which in each case extend along a longitudinal axis and are designed to be identical. Each coupling unit includes a valve unit and a locking unit. The first and the second valve unit are designed to form a fluid connection between the first and the second coupling unit, and the first and the second locking unit are designed to connect the first coupling unit and the second coupling unit mechanically to one another. The first coupling unit includes an actuating element, by actuation of which the first and the second coupling unit can be mechanically connected to one another via the first and the second locking unit and can be fluidically connected to one another via the first and the second valve unit.
