A connector assembly and method of making and ensuring a reliable, fluid-tight connection is provided. The assembly includes a housing a having a wall bounding a bore extending along a central longitudinal axis. The wall has a locking opening, a slot, and a window. A retaining member has a cylindrical wall received in the bore of the housing. The cylindrical wall has a detent received in the locking opening and a locking arm cantilevered by a hinge connection for pivotal movement. The locking arm is spaced from the cylindrical wall by a gap and is received in the slot when the detent is received in the locking opening. A visual indicator attached to the cylindrical wall moves radially outwardly into the window in response to the collar being fully received in the gap to provide visual evidence of a fluid-tight seal between the insertion member and the housing.

A plug-in connection system for fluidic lines, fittings or assemblies, having a housing part and a plug part that can be plugged into a receiving opening of the housing part. A holding element on one of the coupling parts latches with a mating holding element on the other of the coupling parts. The holding element has a spreading surface that, by sliding relative to a corresponding surface of the plug part causes a spreading movement of the holding element, transversely with respect to an axis during installation. In order to improve the plug-in behavior during installation, a spreading contour of the spreading surface engages a mating contour in such a way that, while being plugged in, the spreading travel (Sw) of the holding element changes in a non-linear manner, depending on the status of installation.

A push-in connector for releasably connecting the ends of two media lines consists of a push-in part (2) and a socket part (1) composed of a first socket section (3) and a second socket section (5). In the installed condition, the push-in part (2) is axially latched in the second socket section (5) and accommodated in a manner that is rotatable about its axis, whereas the second socket section (5) can be accommodated in the first socket section (3) at different rotational angles about the common axis (18) in an axially latched manner. The second socket section (5) carries an actuation element (7) that is movable between a latched position shown by an axial pull-out safety device of the push-in part (2) and an unlatched position in which this pull-out safety device is lifted. This embodiment means that the rotational angular position of the second socket section (5) carrying the actuation element (7) with respect to the push-in part (2) as well as to the first socket section (3), and thus the actuation position of the push-in connector, can be adapted to the respective installation conditions, such that unencumbered access to the actuation element (7) is obtained.

A fluidic connection assembly and methods for quickly connecting or disconnecting a tube to a port by hand and without the use of tools. A body is adapted to receive a tube therethrough, and may have at least two sides which are hinged. Each of the hinged sides has corresponding latching portions or projections located near a lower end of the body. These projections are adapted to fit into a port or other fitting and be securely held in place. The assembly may include a tube extending through a body and through a spring located between the end of the body and the end of the tube, whereby the spring exerts a force directly or indirectly against the end of the tube and against the body, thus holding the tubing securely and sealingly engaged in the port when the assembly is connected. The body may further comprise an additional body or an adapter, and/or a cap and latch. A second spring may be used to push a projecting member into a groove or notch of an adapter when an end of the adapter is inserted into one end of the latch or the body. The fluidic connection assembly is useful in analytical instrument systems, such as for in vitro applications and/or in high pressure applications, among other things, and may be used in methods for connecting, or disconnecting, tubing or a fluidic connection assembly from a port or other fitting or connection.

A lock (10) for a tubular connection, blocked axially in a first tubular element and defining an axial opening (14) receiving a second tubular element provided with a circular collar, said lock (10) comprising elastically deformable cradles provided with inside bevels (13) designed so that, while the second tubular element is axially engaged, they move radially apart under the effect of the axial pressure of the circular collar, allow same to pass through, and then move back in to clamp behind the circular collar and to co-operate therewith to lock the second tubular element axially in the first tubular element. Each cradle (11) is provided with a raised axial ridge (15) with a width (l) less than the width (L) of the cradle (11), and is intended during the axial engagement, to receive the axial thrust from the circular collar. A tubular connector is obtained with such a lock (10).

The invention relates to a fuel dispensing unit comprising a fuel conduit comprising an external annular bead, and a locking member comprising inwardly extending resilient tongues and the being arranged to retain the fuel conduit in a locked position and receive the fuel conduit in an open position, wherein the external annular bead of the fuel conduit is arranged to put the locking member in the open position when receiving.

A device for connecting two tubular objects has a connection piece housing and a sleeve-like element. The connection piece housing having a sleeve portion with an insertion opening and with at least one radially continuous cut-out. The sleeve-like element being complementary to the insertion opening for insertion into the insertion opening. The sleeve portion having at least one first engagement element and the sleeve-like element having at least one second engagement element, which mutually correspond in order to lock the sleeve-like element in the sleeve portion and which can be moved from an open relative position into a locked relative position.

Couplers are described herein. A coupler includes a coupler body, a plurality of first retaining fingers, and a plurality of second retaining fingers. The coupler body includes a first end and a second end, and defining a cavity, the cavity configured to receive a first connector and a second connector. The plurality of first retaining fingers are configured to engage against a collar of the first connector to prevent axial motion of the first connector relative to the coupler. The plurality of second retaining fingers are configured to engage against a shoulder of the second connector with a retention force, and release the second connector by radially expanding in response to a pullout force exerted on the second connector exceeding the retention force.

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 dual-latch system requiring two distinct and sequential operations to verify that a proper connection has been made is disclosed. In the first operation, the fluid line is installed into the quick connector and is attached. In the second operation, the fluid line is locked into the quick connector using a separate sliding lock latch. The connector assembly comprises a housing having an inner bore for receiving a portion of the fluid line, a spring latch having radially-spaced engaging bodies for engaging the raised upset or bead of the fluid line, and a sliding lock latch having spring release interference abutments. The sliding lock latch is movable from an unlocked position in which the abutments allow movement of the engaging bodies relative to the raised upset or bead to a locked position in which the abutments restrict movement of the engaging bodies to the raised upset or bead engaging position.
