A method for manufacturing a pipe, the method comprising: a step of fastening a second mechanical quick connection member to a rectilinear hollow tubular body, a step of positioning the rectilinear hollow tubular body in a bending machine so that the angular coding mechanism of the second mechanical quick connection member is in a reference angular position with respect to said bending machine, and a step of bending the rectilinear hollow tubular body as a function of said angular reference position.

A fitting for a pipe generally includes a saddle for coupling the fitting to the pipe and a tap for establishing fluid communication between the fitting and the pipe. The saddle defines a channel extending generally longitudinally through the saddle, and the channel is free of threads. And, the tap is configured to fit within the channel of the saddle for establishing the fluid communication between the fitting and the pipe.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in spin weld engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

A fitting for a pipe generally includes a saddle for coupling the fitting to the pipe and a tap for establishing fluid communication between the fitting and the pipe. The saddle defines a channel extending generally longitudinally through the saddle, and the channel is free of threads. And, the tap is configured to couple to the saddle within the channel of the saddle. A press for installing the fitting to the pipe generally includes a housing configured to releasably couple to the fitting, and a spike configured to releasably couple to the housing and extend at least partly through the fitting for piercing the pipe to thereby allow at least part of the fitting to be inserted into the pipe through the piercing in the pipe to thereby establishing fluid communication between the fitting and the pipe.

A quick fit connector is disclosed for the return line of fuel injectors in an internal combustion engine. The connector includes a T- or L-shaped connector body having at least one connection branch insertable in a fuel return port of a fuel injector, a lower plate, an upper plate and a spring clip. The upper plate is slidingly mounted on the spring clip and the connector body and is movable between an unlocked position, in which the spring clip is in unloaded condition and free from any engagement with the fuel injector, and a locked position in which the spring clip is in loaded condition and engages the fuel injector and the lower plate.

An insulated subassembly for connecting pipelines, containing two insulating half shells made from an insulating plastics, in each case a housing half shell surrounding an insulating half shell, wherein the housing half shell surrounds the outer peripheral surface of the insulating half shell, and at least one hinge connecting the housing half shells, wherein the insulated subassembly contains at least one coupling, preferably quick couplings, positively surrounded by the insulating half shells, and integral closure elements are arranged on the housing half shells.

A drip irrigation lateral connector to a feeder pipe, a feeder pipe adapted for mounting those connectors and an irrigation system comprises a feeder pipe with those connectors and drip irrigation laterals that are mounted to those connectors by standard drip irrigation lateral connectors, wherein each of those connectors comprising a bushing and a sleeve element and wherein the sleeve is formed with a multi-armed circumferential array that are adapted for snap mounting of said sleeve into said bushing or disassembly from it by linearly pushing the sleeve towards the bushing or linearly retrieving the sleeve from the bushing while disconnecting the sleeve's multi-armed circumferential array from the bushing.

A quick pipe connector includes a connector body, a sealing ring, a securing ring, an engaging member and a coupling sleeve. The engaging member is arranged to bias against the securing ring and includes a plurality of catching claws. The coupling sleeve includes a main sleeve member and an extension sleeve extending from the main sleeve member to engage with the connector body in such a manner that when a pipe is inserted in the connector body, the extension sleeve, the sealing ring, the securing ring and the engaging member are securely biased and retained between the connector body and the main sleeve. The catching claws are arranged to securely bias against an external surface of the pipe while the extension sleeve is arranged to bias against an external contour of a connecting portion of the connector body.

A connector apparatus featuring a main pipe with first and second opposed ends. Each has a corresponding male-threaded fastening section for mating with the complimentary female-threaded fastening section on a respective conventional pipe-locking ring or collar. A valve-housing for supporting a one-way flow valve assembly interiorly, and a riser mounted on and supported by the valve housing for ultimate connection to the output or exhaust nozzle of a medical scavenger device.

A connection arrangement device for making a secure connection with at least one tube in a fluid line includes at least one adapter body having a passage bore forming at least one fluid channel with at least one outlet and a receptacle, a mating block formed with at least one longitudinal channel receiving the at least one adapter body, and the at least one adapter body includes a retention feature formed in the receptacle and coupled to the mating block such that the at least one adapter body is securely retained in the mating block. In particular, the retention feature of the adapter body is formed with an annular lip at an end portion of the receptacle to be coupled with the mating block.
