A quick coupling for joining two fluid lines includes a first part which has a projection with a sloping surface directed towards one axial end and a stop face directed towards the other axial end, and a second part which has at least one bracket a catch engages behind the stop face in a locked position. An assembly indicator is arranged next to the catch. In the locked position, the indicator projects outward beyond a catch segment of the bracket on which the catch is located, but, in the unlocked position, the indicator projects outward at most as far as the catch segment.
Description
BRIEF DESCRIPTION OF THE DRAWING
In the drawing:
FIG. 1 is an exploded view showing a quick coupling before its two parts are joined;
FIG. 2 is a view, partially in section showing the quick coupling in its assembled state;
FIG. 3 is a perspective view of the second part; and
FIG. 4 is a top view of the second part of the quick coupling.
Claims
1. A quick coupling for joining two fluid lines, the coupling comprising a first part having a projection with a sloping surface directed towards an axial end and a stop face directed towards another axial end, and a second part having at least one bracket with a catch, wherein the catch engages behind the stop face in a locked position, an assembly indicator being arranged next to the catch, wherein the indicator, in the locked position, projects outward beyond a catch segment of the bracket on which the catch is located, but, in the unlocked position, the indicator projects outward at most as far as the catch segment.
2. A quick coupling in accordance with claim 1, wherein the assembly indicator is rigidly connected with the second part.
3. A quick coupling in accordance with claim 1, wherein the assembly indicator has an indicator segment of the same thickness as the catch segment.
4. A quick coupling in accordance with claim 3, wherein in an unassembled state of the second part, the outer surface of the indicator segment is flush with the outer surface of the catch segment.
5. A quick coupling in accordance with claim 3, wherein the indicator segment is connected with the second part by a spring arm.
6. A quick coupling in accordance with claim 5, wherein the indicator segment is connected with the spring arm by a transitional segment of decreasing thickness.
7. A quick coupling in accordance with claim 1, wherein the assembly indicator is arranged within the bracket in the circumferential direction.
8. A quick coupling in accordance with claim 1, wherein the assembly indicator has a tip that points in the axial direction.
9. A quick coupling in accordance with claim 1, wherein the axial distance between the assembly indicator and the catch segment is at most as great as the axial extent of a circumferential surface of the projection that follows the stop face.
10. A quick coupling in accordance with claim 1, comprising at least two brackets with catches wherein each catch has an associated assembly indicator.
11. A quick coupling in accordance with claim 10, wherein the brackets are connected with each other by an elastically deformable ring.
