A wedge clamp quick release connector has a main body, a positioning mount, and a quick connecting device. The quick connecting device has a sliding sleeve, at least one wedge clamp and a sleeve spring. The sliding sleeve has a spring recess and a clamp recess. Each wedge clamp is moveably held in the positioning mount, and has a stop portion and a wedge portion. The stop portion has an external surface and a stop plane, and the wedge portion protrudes from a middle of the stop plane and has an internal surface opposite the external surface and two bevels formed on two edges of the internal surface. The sleeve spring is mounted in the spring recess of the sliding sleeve. The engagement between the connector and a corresponding plug is in reliable surface contact by corresponding bevels of each wedge clamp and the plug.

A method for coupling a fitting to a tubing end includes pressing a collar over the outer surface of the tubing until the strain on the collar in the hoop direction is at a predetermined level, or pressing a collar with a predetermined axial load.

A coupling device for connecting media-conducting lines has a one-part or multi-part first coupling section and a one-part or multi-part second coupling section. At least one locking element is fastened with at least one connecting section to the first coupling section and is provided with one or more locking arc sections extending in a circumferential direction between the first and second coupling sections. The second coupling section has a locking section extending circumferentially at least partially about a circumference of the second coupling section. At least one of the one or more locking arc sections interacts with the locking section.

A quick disconnect incorporates a male component (nipple) and a female component (socket) that cooperate to form the fluid tight coupling. The nipple at the mating end includes at the outer surface a stepped end forming first and second diameters that are inserted into the socket. The socket includes first and second sleeves, where only the precise stepped end will fit through the sleeves and open the valve of the coupling. The internal fluid path remains identical across all variations of the stepped end and mating sleeves, and many different variations of the quick disconnect valve can be constructed with only minor changes to the stepped end and sleeves.
