Some fluid coupling devices described herein are configured as non-spill fluid couplings. In addition, some embodiments described in this document relate to fluid coupling devices that are constructed modularly, and to modules that can be universally incorporated into the construction of multiple different types of fluid couplings. Further, fluid handling component coupling members are described.

A system for quick connection between a female end piece provided with a U-shaped locking clip and a male end piece fitted therein, the wall of the female end piece having opposite slits through which the arms of the U-shaped locking clip protrude into the passage of the end piece and the wall of the male end piece having an outer groove lockably receiving the clip arms in a final fitted state of the male piece in the female piece, locked by the clip. Also included is a part forming a removable prestressing element for the clip with housing sites engaging the two free sections in a first resting configuration, and in at least a second prestressed configuration in which the arms are more separated than in the resting configuration but less than during the passage of the maximum outer section of the male end piece.

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

An expansion ring for a fluid connector including a including a first end, a second end, a radially outward facing surface, and a through-bore, wherein the expansion ring is slidably engaged with the connector body.

An aseptic coupling assembly, includes a first connector and a second connector. The first connector includes a first housing, a first valve member, and a first spring that biases the first valve member towards the second end of the first housing to a first closed position. The second connector includes a second housing, a second valve member, and a second spring that biases the second valve member towards the second end of the second housing to a second closed position. The first valve member is slidable away from the first closed position within the first housing to compress the first spring and the second valve member is slidable away from the second closed position within the second housing to compress the second spring. The coupling assembly further includes a seal that prevents fluid from contacting the first spring and the second spring.

A connector system including a plurality of connectors having substantially identical structure each defining a pair of fluid conduits wherein a first one of the pair of fluid conduits terminating in a male fitting and a second one of said pair fluid conduits terminating in a female fitting wherein the male fitting and the female fitting of a pair of connectors mate in a fluid transmission connection.

Provided is a connector to be connected to a first pipe including a bulged portion. The connector includes a retainer. The retainer is movable between a standby position and a restraining position. The retainer includes a locking leg and a biasing leg. The locking leg includes a locking part to be locked to a connector body when the retainer is in the standby position and when the retainer is in the restraining position. The locking leg moves radially outward by contacting with the bulged portion, to thereby release locking of the locking part. The biasing leg is elastically deformed radially outward by contacting with a leading end portion of the first pipe, which is located on a leading end side with respect to the bulged portion, to thereby bias the retainer in a direction toward the restraining position.

Connecting device (1), comprising: •—a bush (2), •—an end piece (6) which can be inserted into the bush (2) and is provided with a collar (7), •—a locking device (8) comprising an annular lock (9) which is radially movable inside the bush (2) and a return member (10) for returning the lock (9) to a locked position for retaining the collar (7) of the end piece (6) beyond the lock (9), •—a visual locking indicator (11) which is radially movable between an extended position of the bush (2) and a retracted position and is provided with tabs (12) for returning to the extended position. When the collar (7) of the end piece (6) is inserted beyond the lock (9), the indicator (11), which has the shape of a ring (110), surrounds the collar (7) of the end piece (6) retaining the indicator (11) in the retracted position and the tabs (12) for returning the indicator (11) are axially offset from the ring (110) with respect to direction of insertion of the end piece (6) in the bush (2).

This document describes devices and methods for reducing liquid spillage, such as fluid coupling devices that include one or more apertures that reduce spillage when the fluid coupling devices are disconnected. In some embodiments, the one or more apertures are designed with features to increase a level of acceleration that liquid within an internal volume of the fluid coupling devices would need to be exposed to in order to spill from the internal volume via the one or more apertures.

Couplings are disclosed herein. A plug of a coupling includes a plug body and a socket interface coupled to the plug body. The socket interface includes a shoulder extending axially outward from the plug body, a neck extending axially outward and radially inward from the shoulder, and a socket guide extending axially outward and radially outward from the neck.
