A connecting union joint with smart connection of an easy-flowing pipe system includes a joint body, wherein an end of the joint body is provided with a pipe connecting device which includes a sliding base, a snapping tooth piece, a reset spring, a spring pad and a snapping ring. The joint body is internally provided with a snap slot. The reset spring is arranged between the spring pad and the sliding base. The sliding base is evenly provided with a plurality of through openings. tooth The snapping tooth of the snapping tooth piece deeply extend into an inner wall of the sliding base and are snapped with an outer peripheral surface of the pipe. An inner wall of the joint body is provided with a moving area for allowing the snapping tooth piece to move therein.

An assembly includes a first hub having a body and an end surface, first and second openings defined in the body and a plurality of segmented collets positioned around the body. A locking mandrel is operatively coupled to the body, wherein the locking mandrel is adapted to engage the plurality of segmented collets, and a latching/release mechanism is positioned at least partially within the first and second openings defined in the body, wherein the latching/release mechanism is adapted to be positioned in a first position wherein the locking mandrel is in an unlocked and loaded position and in a second position wherein the locking mandrel is released and engages the plurality of segmented collets so as to couple the first hub to a second hub.

A coupling connection device includes a line coupling connector and a wind guard. The line coupling connector has first and second coupling elements, fitted together in an axial direction. Arresting means of the first coupling element engage with the second coupling element. The wind guard has a plastic shell with a first part-shell and a second part-shell, enclosing a receiving space, and forming first and second line openings, which connect the receiving space to the surrounding region. The first coupling element is coupled in an axially fixed manner in the axial direction to the first part-shell and/or the second part-shell in the receiving space by interlocking engagement. By a movement of the wind guard in the axial direction and away from the second coupling element, an arresting means can be actuated and the first coupling element can be separated from the second coupling element.

A hydraulic tube connector for vehicle may include a connector body including a through hole into which a tube having a tube protrusion protruding outward is inserted, and a pair of guide grooves formed around the through hole and a coupling member configured to couple the tube with the through hole of the connector body, wherein the coupling member includes a tube coupling portion configured to surround the tube and a pair of coupling guides configured to be inserted into the pair of guide grooves.

An assembly includes a first hub having a body and an end surface, first and second openings defined in the body and a plurality of segmented collets positioned around the body. A locking mandrel is operatively coupled to the body, wherein the locking mandrel is adapted to engage the plurality of segmented collets, and a latching/release mechanism is positioned at least partially within the first and second openings defined in the body, wherein the latching/release mechanism is adapted to be positioned in a first position wherein the locking mandrel is in an unlocked and loaded position and in a second position wherein the locking mandrel is released and engages the plurality of segmented collets so as to couple the first hub to a second hub.

An extraction connection system for portable machine tools includes at least one tool connection element, at least one suction apparatus connection element, and at last one fixing unit. The at least one tool connection element is configured to be connected to the at least one suction apparatus connection element. The at least one fixing unit includes at least one movably mounted fixing element configured to fix the at least one tool connection element and the at least one suction apparatus connection element against a movement relative to each other in at least one direction.

A high pressure dispensing nozzle for providing fuel from an inlet reserve to a connector of an outlet receptacle, including a generally tubular nozzle construction having an outer sleeve extending from adjacent a proximal end towards a distal end of the nozzle construction, an internal passageway construction disposed within the outer sleeve, and a plurality of radially movable jaw members disposed between the internal passageway construction and the outer sleeve extending to near the distal end of the tubular construction, wherein the internal passageway construction includes interacting components responsive to insertion of the connector into the distal end and engagement thereof with the internal passageway construction to effect movement of the jaws to lock the connector in engagement and to establish a fuel passageway through the nozzle construction for the delivery of fuel therethrough and wherein the internal passageway construction components include a pistonably slideable outlet tube construction that not only serves as part of the fuel delivery passageway through the nozzle construction but also both as a control for locking the jaws and the outer sleeve in a fueling configuration and as a valve construction for allowing and preventing fuel flow through the nozzle construction. The nozzle preferably is also responsive to the introduction of fuel thereinto to pressure lock the outer sleeve in a fueling configuration and additionally operates to prevent the dispensing of fuel in the event that a proper and correct connector is not locked into engagement for fuel dispensing.

A garden fluid flow connector arrangement including a first connector portion and a second connector portion which is arranged to inter-engage with the first connector portion to form a fluid path through the connector arrangement. The first connector portion includes a first body portion and a locking portion mounted on the first body portion for rotation about an axis of the first body portion and the second connector portion includes a second body portion carrying an engaging portion. The locking portion is rotatable relative to the first body portion and the engaging portion between a first position in which the first and second connector portions are engaged and held against axial separation by interaction of the locking portion and the engaging portion and a second position for allowing axial separation of the first and second connector portions.
