The invention relates to a fluid coupling (1) with tolerance compensation for the flexible connection of two media-conducting elements. The invention was based on the object of improving a fluid coupling (1) of the described type in such a manner that the use of complicated latching systems for transport can be omitted. This object is achieved in that the fluid coupling (1) has at least one transport securing device (8, 12), by means of which a separation of the components (2, 3) of the fluid coupling (1) from one another prior to installation can be prevented.

A connection to releasably connect and disconnect to a pipe to a fitting provides a pipe fitting body for receiving a pipe and a retaining ring assembly located within the fitting body for retaining and releasing the pipe. The retaining ring assembly has axially extending inwardly angled resilient retaining tabs, each of which has a pipe retaining portion. When the pipe is inserted into the fitting body to an inserted position, the pipe retaining portions engage an indentation on the pipe to retain the pipe in the inserted position. Relative movement of the axially extending inwardly angled resilient retaining tabs with respect to the fitting body from the first locked position to a second unlocked position causes each axially extending inwardly angled resilient retaining tabs to disengage from the indentation on the pipe permitting removal of the pipe from the inserted position in the fitting body.

The present invention provides a quick connector made of plastics material for establishing a snapping connection between a tubular male part (50) and female part (40) of a fluid connection system. The connector has retaining means (10) adapted to be set within the mouth portion (41) of the female part (40) and having first and second flexing members (12, 22) for snapping engagement with the male part (50) and the female part (40), respectively. The first and second flexing members (12, 22) are provided at circumferentially spaced portions of the retaining means (10) so that the overall axial dimensioning of the retaining means (10) is reduced.

The present invention provides a quick connector for establishing a snapping connection between a tubular male part (50) and a female part (40) of a fluid connection system. The connector has retaining means (10) adapted to be set within the mouth portion (41) of the female part (40) and having a resilient member (20) for snapping engagement with both a thickened portion (52) of the male part (50) and an annular groove (42) in the mouth portion (41) of the female part (40) when the resilient member (20), which is held by the retaining means (10) in an axially fixed position, is stretched in the radial direction due to the snapping engagement with the male part (50).

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 quick connect and disconnect system for a fluid coupling includes an axially extending fitting configured to be secured to a fluid conduit, a clip, and a quick connect and disconnect adaptor. The clip is coupled to the fitting and includes a base, a wing extending from the base, and a first lug extending from the first wing. The quick connect and disconnect adaptor includes a first release tab configured to resiliently deflect through an aperture of the adaptor. The adaptor is configured to transfer a compressive force to resiliently deflect the first lug to move the clip in an axial direction from an installed position to an uninstalled position.

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.
