Connection device for connecting tubular components

A connection device comprising:

• a base body with a hose-receiving region, wherein a seal-receiving region is formed in the hose-receiving region and wherein a collet-chuck-receiving region is formed in the hose-receiving region,
• a collet chuck with a connection opening for receiving a line-shaped component, the connection opening having a connection opening diameter, the collet chuck having a plurality of elastically resilient clamping elements distributed over the circumference, the collet chuck being received in the collet-chuck-receiving region so as to be displaceable in the axial direction relative to the base body, the clamping elements being displaceable in the radial direction by axial displacement of the collet chuck relative to the base body, and
• a sealing element, which is arranged in the seal-receiving region and forms a seal between the line-shaped component and the base body;
• wherein the connection device is configured to receive line-shaped components with different line diameters in the hose-receiving region,
• wherein a first axial stop is formed in the base body, having a first cylindrical lateral surface with a first axial stop diameter, and a second axial stop is formed, having a second cylindrical lateral surface with a second axial stop diameter,
• wherein a first type of the line-shaped components with a first line diameter can be attached to the first axial stop, and a second type of line-shaped components with a second line diameter can be attached to the second axial stop,
• wherein the first axial stop has a first end face and the second axial stop has a second end face,
• wherein the first end face and the second end face are arranged spaced apart from one another in the axial direction at an end face distance,
• wherein the first axial stop and the second axial stop are aligned parallel to each other, and
• wherein the second axial stop diameter is between 87% and 99.9% of the connection opening diameter such that the line-shaped components having different line diameters can be secured in the axial direction in the connection device.
