The invention relates to a locking element (30) for detachably fixing a fluid-guiding plug (40) to a connector (10). To facilitate handling during coupling and decoupling, the locking element (30) has at least one spring element (37) or is connected to or engages with such an element, by means of which spring element the locking element is autonomously brought into a locking position with the plug (40) and is held in this locking position. The invention also relates to a locking system for detachable locking of a fluid-guiding plug (40) to a connector (10) in which a locking element (30) of this type is used.

A tube coupling component (4;6) serves for use in a tube coupling system and an irrigation system. The tube coupling component (4;6) comprises a male coupling part (12) opposite a respective female coupling part (11), or a first end fitting (33) opposite a respective second end fitting (34), which tube coupling component (4;6) has an interior pipe (13;31) that extends axially inside an exterior pipe (14;32), wherein the interior pipe (13;31) and the exterior pipe (14;32) are concentric.

The connector comprises a housing having a connection hole where a pipe with a flange is inserted, a retainer having a latching portion that retains the pipe by being arranged at a location facing the connection hole and engaged with the flange, and a checker that is supported by the housing at the retaining position and is movable from the retaining position to the connection confirmation position when the pipe is inserted into the connection hole up to the normal connection position. The checker is configured to release the engagement between the latching portion and the flange, when at the connection confirmation position, by having the retainer that is engaged with the flange of the pipe at the normal connection position pushed to expand the distance of the retainer so that the pipe can be pulled out from the connection hole.

A quick coupling device of the cartridge type, the device comprising a tubular body defining a channel, a retaining washer for retaining the tube in the device, a tubular disconnection pusher that is slidably mounted in the channel, and an anchor for anchoring the coupling device in the socket. The body has one end provided with a retractable ring that projects axially from the end in order to carry internally a sealing member of the coupling device and in order to be suitable for being returned against the body in order to release the sealing member in the socket. The retaining washer is arranged in the retractable ring between the body and the sealing member.

A coupling device (1; 1′) for conduits conveying hydrocarbon liquids and hydrocarbon vapors, in particular for crankcase ventilation conduits, fuel conduits or tank ventilation conduits, includes a coupling body (2) with a connecting piece receiving section (6); and a locking member (4; 4′) for locking into place a connecting piece (24) guided into the connecting piece receiving section (6); wherein the connecting piece receiving section (6) has an installation recess (10) open radially toward the side, and wherein the locking member (4; 4′) can be guided into the connecting piece receiving section (6) laterally in radial direction (MR) by an installation recess (10).

A fluid interaction device for establishing an interaction with a fluid, particularly a brake fluid or a fuel fluid. A housing member accommodates a fluid interaction portion. The fluid interaction portion is adapted to interact with a fluid within the housing member. The housing member further comprises a connection portion which can be connected to a fluid supply element. The connection portion is formed as a weldable, tubular end portion so that the housing member can be connected to a joining portion of the fluid supply element by means of a welded joint.

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 releasable connection assembly for connecting tubing sections is disclosed. The assembly includes a dual lumen male bayonet connector and a female latch connector. The dual lumen male bayonet connector includes a first shaft and a second shaft, where each of the first and second shafts includes a distal sealing portion defining a sealing surface, a proximal coupling portion, and an annular channel. The female latch connector includes a proximal end, two sealing members and a distal end. A kit is also disclosed. The kit includes a dual lumen male bayonet connector, a blood pressure cuff, and two sections of medical tubing. The two sections of medical tubing engage each of the proximal coupling portions of the first shaft and the second shaft and the blood pressure cuff.

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).

A drip emitter for subsurface irrigation includes a valve chamber defining a hollow interior, an entry port and at least one exit port. A flexible diaphragm is mounted in the hollow interior of the valve chamber for movement in response to pressurized water being supplied to the hollow interior through the entry port. The drip emitter further includes a tortuous path water flow channel that limits the flow of water from the hollow interior of the valve chamber to the at least one exit port. A closure member is moved by the flexible diaphragm to open the at least one exit port when pressurized water enters the hollow interior to allow water to be discharged through the at least one exit port. A spring moves the closure member to close the at least one exit port when the supply of pressurized water is shut OFF.
