This connector comprises a tubular connector body made of a plastic material and a receiving sleeve made of a metallic material. Within the receiving sleeve, a separate and additional retaining element made of a plastic material is arranged to form a receiving groove for a sealing element. The connector body forms the first side surface and the base surface of the receiving groove. The second side surface of the receiving groove is formed by an end face of the additional retaining element. The connector body, the receiving sleeve, and the retaining element located within the receiving sleeve define a receiving space for the second connector.The disadvantage is that a separate additional holding element has to be manufactured and at least one additional work step is required when assembling the connector.

[0003] EP 1 912 009 A1 also discloses a plug connection arrangement.

[0004] The object of the present invention was to overcome the disadvantages of the prior art and to provide a pipe connector and a method for its manufacture that is simpler and more cost-effective to produce. Furthermore, a pipe connector assembly and its manufacturing process are to be described.

[0005] This problem is solved by the pipe connector for guiding liquid and / or gaseous media, as well as a pipe connector assembly, as well as the method for manufacturing the pipe connector, as well as the method for manufacturing the pipe connector assembly according to the claims.

[0006] According to the invention, a pipe connector is designed for conveying liquid and / or gaseous media. The pipe connector comprises: a shaped body, a connector body for connecting the shaped body to a pipe to be connected, a seal for sealing the connection between the connector body and the shaped body, wherein the connector body is at least partially formed as a metal forming part, wherein the connector body has an annular space located between a sleeve-shaped first shell section, the cross-section of which substantially surrounds a central longitudinal axis of the connector body in an annular manner, and a sleeve-shaped second shell section of the connector body, the cross-section of which substantially surrounds the central longitudinal axis in an annular manner, wherein the first shell section is surrounded by the second shell section and the first shell section of the connector body is connected to the second shell section at a first end section, in particular integrally connected in the form of a fold, and the shell sections are open to each other at a second end section, thereby forming a pipe receiving side of the connector body, wherein the pipe can be inserted into the annular space of the connector body from the pipe receiving side, and wherein the connector body is pushed onto the molded body from a first end face of the molded body.wherein a recess is formed in the molded body, wherein the first end section of the connector body is pressed into the recess in a form-fitting manner.

[0007] The pipe connector according to the invention offers the advantage that it enables a simple and durable connection between a pipe and a shaped body. The pipe connector can also have a simple and robust design.

[0008] As an alternative to forming a flap between the first and second shell sections, it is also conceivable that the first and second shell sections are manufactured as separate components and connected to each other by means of a joint. Such a joint could be, for example, a weld, a press fit, a folded joint, a crimp, or some other type of connection.

[0009] In a separate manufacturing process for the first and second shell sections, one possible embodiment allows both sections to be formed from metal. Alternatively, the first shell section could be made of a different material than the second. Specifically, the first shell section could be made of a plastic material, while the second section could be made of a metallic material.

[0010] Furthermore, it can be advantageous for the molded part to be made of a plastic material. This offers the advantage that such a molded part can have a robust structure. Moreover, such a molded part can be easily manufactured using an injection molding process. Furthermore, such a molded part can have a geometrically complex structure.

[0011] Furthermore, the molded body can be designed as a connector for joining with a mating connector. This offers the advantage that the pipe connector, together with its mating connector, can form a detachable connection.

[0012] Furthermore, a positive-locking anti-rotation feature can be provided between the shaped body and the connector body. This offers the advantage that the angular position of the shaped body relative to the connector body can be clearly defined and secured against unwanted rotation.

[0013] Another advantageous design is one in which the anti-rotation device includes a projection formed on the molded body, and a recess is formed in the connector body into which the projection engages. These measures allow the anti-rotation device to have a simple design.

Furthermore, it is possible for the recess to partially penetrate a third and a fourth shell section located at the first end section. These measures allow the anti-rotation device to have a simple design. In particular, it is possible for the recess to be formed in the form of a punched-out section.

[0015] Furthermore, it can be advantageous if the projection is positioned in the area of ​​the recess of the molded part. These measures allow the anti-rotation device to have a simple design.

This measure can achieve improved sealing of the pipe connector.

[0017] Furthermore, the sealing groove can be designed to be located on the outside of the first end face of the molded body. This measure can achieve an improved seal of the pipe connector.

[0018] In one particular design, a viewing window may be arranged in the second jacket section, penetrating the second jacket section and allowing a view into the annular space from the outside. This has the advantage of allowing verification of the correct connection of the pipe to the pipe connector.

[0021] The pipe connector assembly according to the invention offers the advantage that it enables a simple and durable connection between a pipe and a shaped body. The pipe connector assembly can also have a simple and robust design.

[0022] In particular, it can be advantageous if the pipe is deformed by crimping the first and / or second jacket section and pressed against the opposite jacket section. This measure can achieve an improved and tight connection between the pipe and the pipe connector.

[0023] Furthermore, a sealing surface can be provided between the pipe and the first section of the casing. This measure can increase the sealing effect between the pipe connector and the pipe.
