A tube coupling including a female connector a body into which a male connector having an annular collar is inserted axially, and a connection element is provided. The connection element extends in a transverse direction within the body of the female connector. The connection element is designed to interfere mechanically with the collar during insertion of the male connector and to move transversely of its own accord towards the inside of the female connector. The connection element includes a locking hook that cooperates with a locking catch provided in the female connector. The hook goes past the catch as a result of the mechanical interference of the collar that drives axial and radial elastic deformation of the connection element. The hook locks against the catch when the connection element is fully pushed into the female connector.

A connector is disclosed that includes a coupler having a socket end fluidically connected by a passage to a stem connected to a first fluid tube. A retainer housing having a cavity in axial alignment with the passage is installed on the coupler socket end and a retainer is installed in the retainer housing in a first position. A second fluid tube having a raised bead formed proximate an end portion of the second fluid tube is permitted to be installed into the retainer housing cavity by the retainer when the retainer is in the first position. Installation of the second fluid tube places the bead in the retainer housing and the end portion of the second fluid tube in the coupler passage providing a fluid path between the first fluid tube and the second fluid tube. The retainer is moved to a second position latching the bead to the retainer housing retaining the second fluid tube to the connector.

The present disclosure is, in one aspect, directed to a locking assembly for securing a sample tube assembly to a sample manifold of a measurement system. The locking assembly includes a ramp block having one or more slots defined therein and configured to at least partially receive a portion of the sample tube assembly. The ramp block also includes a plurality of surface features defined therealong and configured to engage and move the sample tube assembly toward and into engagement with the sample manifold. The ramp block further is movable between a plurality of positions including an open position for allowing the sample tube assembly to be received through the one or more slots or openings, and a closed position substantially sealing the sample tube assembly against or within the sample manifold. Other aspects also are described.

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 quick connector and connector body comprises a coupler portion having a fluid passage connected to a first fluid tube. A valve mounted within the fluid passage is movable between a closed and an open position. A receptacle portion coupled to the coupler portion includes a socket cavity adapted to receive a second fluid tube within the socket cavity that causes the valve to move into the open position allowing fluid to flow through the fluid passage from the first fluid tube to the second fluid tube.

A locking member is mounted to the housing to be able to move in the outer diameter direction by a tapered portion of the tubular body, when the tubular body is inserted. The housing is equipped with slits formed to pass a curved portion bent in the inner diameter direction disposed at a leading-end side of the locking member and to lock with the engagement portion of the tubular body mounted on the housing. A gap is disposed between the curved portion, and the end portion of the slit positioned at a side in an opposite direction to the leading-end side of the locking member, so that there is no contact while at least the locking member is moving.

A fluidic connection device for a fluid circuit of a motor vehicle includes a female fluidic connector, a U-shaped lock, and a locking indicator. The female fluidic connector includes a housing configured to receive a male fluidic connector, by translation along an axis (A). The U-shaped lock is carried by the female connector and includes a pair of elastically deformable legs that arranged substantially in a first plane, perpendicular to the axis (A) and on either side of the axis (A) and being configured to cooperate by elastic snap-fitting with the male connector to ensure retention of the male connector in the female connector along the axis (A). The locking indicator is carried by the female connector and configured to be translated in a second plane, perpendicular to the axis (A), between a first position for releasing the locking indicator and a second position for locking the locking indicator.

A quick connector structure includes a fitting connector, a connector, and a U-shaped positioning snap pin. The fitting connector is a pipe connector, a three-way valve connector, or a washing machine valve connector. The fitting connector is combined with a pipe body. The U-shaped positioning snap pin ensures the stability of the connection between the fitting connector and the connector. The quick connector structure enables rapid positioning and assembly, reducing the assembly difficulty in a smaller or concealed space and achieving the effects of assembly stability and convenience.

A quick connector coupling for making a severable connection with a male member in a fluid line includes a connector body having a through bore for receiving the male member having a tubular shape sized to extend into the through bore of the connector body, a retainer releasably securing the male member within the connector body, and a verifier including at least one arm extending outside the connector body. Further, the verifier is coupled to the connector body and is moved to a latched position from an unlatched position when the male member is securely connected with the connector body. The connector body includes at least one verification element, which is at least partially covered by the at least one arm extending from the verifier in the unlatched position. The verification element of the connector body is uncovered and readable when the verifier is moved to the latched position.

The disclosure herein relates to a quick-connect fitting that provides a leak-proof connection between two components of a waterway. The quick-connect fitting of the present disclosure is releasable and reusable for disconnecting and reconnecting the waterway connection. Moreover, the quick-connect fitting further comprises an audible identifier which identifies the quick-connect fitting has secured the waterway components to be connected.
