A quick connector assembly includes a male adapter portion (24) having an end and a groove (62) formed therein spaced from the end. The male adapter portion has a through bore. A female housing portion (22) has a body having a through bore generally concentrically aligned with the male adapter portion through bore. A ring (26) cooperates with the female housing portion and the male adapter portion. The ring is in a first position when the male adapter is engaged with the female housing and a second position, different from the first position, when the male adapter is other than engaged with the female housing. The first and second positions can be visually different from one another.

A releasable plug connection with a tubular plug-in part, and with a sleeve-shaped receiving part which has an insertion opening through which the plug-in part is insertable into a sleeve interior of the receiving part. At least one annular groove is provided on the inner circumference of the receiving part, in which an annular seal is arranged which provides sealing in the annular gap between the inner circumference of the receiving part and the outer circumference of the plug-in part. The insertion opening opens out in a first interior portion of the sleeve interior that is configured as a cross-sectional widening in relation to an adjacent second interior portion and is delimited by an annular shoulder, and an insertion sleeve is insertable in the first interior portion of the sleeve interior, its peripheral edge directed towards the annular shoulder being spaced apart from the annular shoulder to form the annular groove between the peripheral edge of the insertion sleeve and the annular shoulder.

A medium connector including a passage configured to allow for the flow of medium, and a multi-portion engagement surface positioned about the passage. The multi-portion engagement surface includes a first surface portion, and a second surface portion. The first surface portion is configured to provide an interference fit with a corresponding sealing surface of a mating connector. The second surface portion is configured to provide a clearance fit with the corresponding sealing surface of the mating connector. The ratio of the first surface portion and the second surface portion is selected to regulate an engagement force between the medium connector and the mating connector.

A hinged connection device includes first and second tubular components around a main axis which respectively include a first male hinge member provided with an end head shaped as a spherical segment and a second female hinge member provided with a complementary seat receiving movably inside the end head of the first member. The first member is configured to be housed at least partially inside the first component and to be assembled to the second component throughout the second member. The second member is configured to be mounted around the second component and assembled to the first component over the first member such that the two tubular components are assembled together by the reciprocal intersection of the two hinge members.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a sterile connection for drug delivery. In some embodiments, the fluid coupling devices can be implemented as multi-use, sterile fluid coupling devices that are configured to reduce the likelihood of fluid spillage when being disconnected.

A connection device for connecting a tubular connector provided with an annular collar to an item of equipment comprising a passage, the connection device comprising:—a connection end fitting connecting to the passage of the item of equipment, the connection end fitting being formed by a tubular body with a head mounted thereon, the head being provided with a through-opening and comprising an ellipsoidal annular groove;—a locking ring having at least two longitudinal flexible legs for insertion into the connection end fitting, each having an outer surface bearing at least one lug intended to engage in the annular groove in order to hold the locking ring secured to the connection end fitting. The two flexible legs can be deformed and closed on the tubular connector in order to abut their free ends against the collar when the male connector is inserted longitudinally into the locking ring.

A high-voltage battery component includes a connection device for connecting a coolant line for a coolant to a heat sink of a high-voltage battery. The connection device has a connection part, which is connectable to the heat sink, and a sealing element arranged at the end of the connection part for providing a seal between the connection part and the heat sink. The connection device includes a spreading part, which is movable relative to the connection part. The spreading part, by pushing into the connection part, can be transferred from an insertion position for inserting the connection part into the heat sink into a sealing position. In the sealing position, the spreading part spreads the sealing element radially outward such that the sealing element can be placed in a sealing manner against the heat sink when the connection part is plugged into the heat sink.

A system for sensing a physical property of a medium inside a conduit includes a radio frequency identification (RFID) reader arranged to transmit electromagnetic signals in at least one radio frequency. An RFID tag receives the least one radio frequency and exchanges the received radio frequency to electrical energy powering the RFID tag. An included sensor electrically connected to the RFID tag receives the electrical energy from the RFID tag and powers the sensor to obtain measurement data of at least one physical property of the medium and transmit the measurement data to the RFID tag. The RFID tag transmits the measurement data to the RFID reader using the at least one radio frequency.

A dispensing fitment assembly includes a fitment assembly and a dispensing probe. The fitment assembly includes a fitment housing and a plug. The fitment housing is configured to operatively couple to a container opening of a fluid container. The plug is positioned within an interior portion of the fitment housing. The plug is slidingly movable between an open and closed position. Engagement between the dispensing probe and the interior surface of the plug is configured to move the plug from the closed position to the open position. Disengagement between the dispensing probe and the interior surface of the plug is configured to move the plug from the open to closed position.

The invention relates to a reversibly detachable fluid line coupling (1), at least having a coupling sleeve (2), a locking element (3) and a coupling plug (4) with a locking collar (41). The invention was based on the object of creating a fluid line coupling of the type described at the outset, the locking state of which can easily be checked automatically, with a visual check being preferred. This object is achieved in that the coupling has actuating/signaling surfaces (312) which are only visible when the coupling is in the unlocked state.
