Connection systems and connecting methods for transferring fluids. According to one embodiment, the connection system includes an active unit having an active connection assembly connected to a first supply conduit and a passive unit including a passive connection assembly connected to a second supply conduit. The active connection assembly includes a first connector coupled to the first supply conduit, an active sleeve externally coupled to the first connector, and sealing means fixed inside the active sleeve which, in a fluid disconnection position, surrounds the first connector, preventing the outflow of fluid from the first connector. The passive connection assembly includes a second connector connected to a second supply conduit, the active unit including drive means for causing the movement of the active sleeve between the fluid disconnection position and a fluid connection position without axially moving the first and second connectors.

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 joint that is coupled to a cylindrical fluid discharger whose peripheral edge expands radially outward. The joint includes a cylindrical coupler that is coupled to the fluid discharger and has a male screw on an outer peripheral surface thereof, an engager that engages with the peripheral edge, and a tubular body that has a female screw to be coupled to the male screw on an inner peripheral surface thereof, and switches between a first state in which the attachment and the detachment of the fluid discharger and the joint are allowed and a second state in which the attachment and the detachment of the fluid discharger and the joint are restricted.

An adapter for connecting a water pipe and a high-pressure spray gun includes a connection assembly, a clamping assembly, and a covering member. The connection assembly includes a connector body defined by a side wall and extending between a proximal end and a distal end, and a chute that extends along the connection body between the proximal and distal ends. The water pipe is coupled along the proximal end and the spray gun is coupled along the distal end. The chute includes grooves, and tapered regions seamlessly extending below from the grooves. The clamping assembly is operatively coupled to the connector body. The covering member sleeves over the connection assembly to movably engage with the clamping assembly, and is pressed and released to realise the buckle to move down from the grooves towards the tapered regions and back from grooves to the tapered regions, to clamp the water pipe.

A connector for use with a dialyzer to connect a conduit from a dialyzer with a conduit from a dialysate source. The connector includes a sleeve (female component) and a collet (male component). The sleeve has a generally cylindrical shape with an opening at one end having a circular shape with at least one slot positioned along the periphery of the circular shape. The sleeve also includes at least one flexible finger having a barb at a free end. The collet is configured to be housed within an interior chamber of the sleeve and has first and second gaps to house the barbs and first and second deflectable flanges to lock into recesses in a conduit.

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.
