A gardening fluid connection device contains a body including multiple retainers, a resilient element, and a fitting sleeve including multiple spaced engagement teeth. The resilient element abuts against the body and the fitting sleeve. The body includes a stop rib, and the multiple spaced engagement teeth are pushed by the resilient element to abut against the stop rib. The body includes at least one retaining element, each retaining element is located on a first side of each spaced engagement tooth, and a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, hence the fitting sleeve is rotated reciprocatingly to open or close of the gardening fluid coupling device by using the stop rib, each retaining element, each spaced engagement tooth and the resilient element, and each retaining element is stopped when moving to a second side of each spaced engagement tooth.

A connector for a component of a medical breathing circuit. The connector comprises an inner body and an outer body. The outer body is configured to be slidable along the inner body between each of an inoperative orientation and an operative orientation with respect to the inner body. The outer body and the inner body are configured to be in engagement or in an operative association with each other when the outer body is provided in the operative orientation. The outer body and the inner body are disengaged from each other or in an inoperative association with each other when the outer body is provided in the inoperative orientation. At least one or each of a surface of the inner body or a surface of the outer body comprises of a surface relief feature(s) providing for a resistance to the outer body being moved from the inoperative orientation to the operative orientation.

A coupling device is provided for mounting on a bib of a faucet to releasably secure a hose or some other component to the bib. The coupling device includes an engagement surface, a gasket ring, a clamp assembly and a locking assembly. The coupling device is configured so that the clamp assembly can be actuated to mount the coupling device on the bib. The gasket ring is configured to be compressed between the engagement surface and the bib to enable liquid to flow from the bib into the coupling device and out of it into the hose or other component without leakage. The locking assembly is configured to lock the coupling device on the bib, but is releasable when desired to dismount the coupling device from the bib.

An inflatable air nozzle connector comprises a clamping component, an airtight ring and a shell sleeve, the airtight ring is disposed in the clamping component; the shell sleeve is capable of slidably sleeving on an outer periphery of the clamping component and displacing between a pressing position and a releasing position. When the shell sleeve displaces downward to the pressing position, the clamping component is pressed, so that clamping jaws of the clamping component compress the airtight ring; when the shell sleeve displaces upward to the releasing position, the clamping jaws are not pressed, and the clamping jaws do not compress the airtight ring. When a user pushes or pulls the shell sleeve single-handedly, the inflatable air nozzle connector is capable of airtightly sleeving on an air nozzle of a tire, or separating from the air nozzle of the tire, making operation of inflating tire more convenient.

This document describes fluid coupling devices for fluid handling systems. For example, some embodiments described in this document relate to fluid coupling devices that snap together, and are then secured to each other using a collar and collet mechanism. Some fluid coupling devices described herein are well suited for use in systems that provide fluid cooling for heat generating devices such as computer hardware. The fluid coupling devices described herein are also suitable for many other uses.

This female element of a quick connector that connects to a male element and has a hollow body, which extends along an insertion axis and which delimits a receiving volume for the male element. Radial openings, formed in the body along a radial axis, open into the receiving volume. Each radial opening receives a latch, translatable in relation to the body along the corresponding radial axis, between a locked and an unlocked position. The female element has an actuating ring arranged about the body and translatable between a locked and an unlocked position. The ring has guide grooves, which interact with pins of each latch. The guide grooves associated with each latch are geometrically carried by a guide plane inclined in relation to the insertion axis so that each latch is driven between its locked and unlocked positions when the actuating ring is moved between its locked and unlocked positions.
