Abstract

A connection device for the plug connection of at least one media line includes a housing part with at least one reception orifice for plugging in a plug portion connected or connectable to the at least one media line. The housing part includes a basic part and an insert part. The basic part is releasably connected with a form fit to the insert part via a latching connection. The latching connection holds the insert part releasably and is formed by a C-shaped spring clip which is seated on the outside of the basic part and engages with at least one latching extension radially through an orifice of the basic part into a circumferential latching groove of the insert part.

First claim

The invention claimed is:

1. An assembly tool and components to be assembled into a connection device, the assembly tool comprising: a radially elastic shank being subdivided by longitudinal slots into radially spring-elastic spring arms, the spring arms having outwardly protruding radial holding bosses and outwardly protruding radial actuating bosses wherein the radial holding bosses are located closer to free ends of the spring arms than the radial actuating bosses, the radial holding bosses and the radial actuating bosses defining holding zones, the components comprising a clamping ring and an insert part, the clamping ring and the insert part being located on the spring arms and arranged in an axial direction at the holding zones by radial inward deformation of the spring arms, wherein the assembly tool can be introduced into part of the connection device together with the clamping ring and the insert part, and wherein the radial actuating bosses have a greater radial height than a radial height of the radial holding bosses and wherein the spring arms are deformed radially inward by the radial actuating bosses to an extent such that the radial holding bosses can be drawn out of the part of the connection device.

2. The assembly tool and components according to claim 1 , wherein the spring arms are circumferentially connected with each other via connecting sections at the free ends of the spring arms which are located opposite a grip section of the assembly tool, and the grip section is configured to allow the assembly tool to be grasped by a user to remove the assembly tool from the connection device.

3. The assembly tool and components according to claim 2 , wherein the components further comprise a circumferential seal and the spring arms further comprise first holding zones between the radial holding bosses and the radial actuating bosses for the circumferential seal and the clamping ring and further comprise second holding zones between the radial actuating bosses and the grip section for the insert part, in such a manner that when the spring arms are deformed radially inward, initially the insert part and then subsequently the clamping ring and the circumferential seal can be placed onto the spring arms from the free end.

4. The assembly tool and components according to claim 1 , wherein the components further comprise a circumferential seal and the spring arms comprise a first holding zone between the radial holding bosses and the radial actuating bosses for the circumferential seal and the clamping ring, and further comprise a second holding zone between the radial actuating bosses and a grip section for the insert part, in such a manner that when the spring arms are deformed radially inward, initially the insert part and then subsequently the clamping ring and the circumferential seal can be placed onto the spring arms from the free end.

5. A combination comprising an assembly tool and a connection device, the connection device including a basic part and components received within the basic part, the components including an insert part, a clamping ring engaging the insert part and a circumferential seal engaging the basic part, the assembly tool configured to assemble the components into the basic part of the connection device, the assembly tool including a radially elastic shank being subdivided by longitudinal slots into radially spring-elastic spring arms, the spring arms having outwardly protruding radial holding bosses and outwardly protruding radial actuating bosses wherein the radial holding bosses are located closer to free ends of the spring arms than the radial actuating bosses, the radial holding bosses and the radial actuating bosses defining holding zones for the components which can be arranged in an axial direction at the holding zones by radial inward deformation of the spring arms, wherein the assembly tool can be introduced into the basic part together with the components, and wherein the radial actuating bosses have a greater radial height than a radial height of the radial holding bosses wherein the spring arms are deformed radially inward by the radial actuating bosses to an extent such that the radial holding bosses can be drawn out of the basic part by being moved, essentially free of contact and friction, through all of the components.
