Abstract
A coupling system, in particular for tubular elements, with a socket element and a plug-in element, wherein a locking element is also provided, wherein the socket element has a tube-like receiving region for receiving the plug-in element, wherein the locking element has a securing element which is supported in the plugging-in direction against a securing mating element of the plug-in element and the locking element is supported with a locking device against a locking mating device on the socket element, and therefore the socket element and the plug-in element are secured axially indirectly via the locking element and thus via the securing element, the securing mating element and the locking device and the locking mating device.
Claims15
A coupling system for tubular elements, comprising:
- a socket element and a plug-in element, wherein a locking element is also provided, wherein the socket element has a tube-like receiving region for receiving the plug-in element, wherein the locking element has a securing element which is supported in a plugging-in direction against a securing mating element of the plug-in element and the locking element is supported with a locking device against a locking mating device on the socket element, and therefore the socket element and the plug-in element are secured axially indirectly via the locking element and thus via the securing element, the securing mating element and the locking device and the locking mating device;
- wherein the securing element is configured as a front edge of a locking tongue, wherein the locking tongue is formed on a circumference of the locking element and extends with a free end in the plugging-in direction, and wherein the locking element is positioned axially inward of an axial end of socket element;
- wherein at least one securing element and at least one locking device are arranged in the locking element, wherein the securing elements and the locking devices are in each case arranged lying diametrically opposite.
A coupling system for tubular elements, comprising:
- a socket element, a plug-in element, and a locking element, wherein the socket element has a tube-like receiving region for receiving the plug-in element, wherein the locking element has a securing element which is supported in a plugging-in direction against a securing mating element of the plug-in element and the locking element is supported with a locking device against a locking mating device on the socket element, such that the socket element and the plug-in element are secured axially indirectly via the locking element and thus via the securing element, the securing mating element and the locking device and the locking mating device;
- wherein the securing element is configured as a front edge of a locking tongue, wherein the locking tongue extends with a free end in the plugging-in direction, wherein the securing mating element comprises part of an annular flange on the plug-in element, and wherein the free end includes a portion that is located radially outward of and over a radially outer edge of the annular flange.
A coupling system for tubular elements, comprising:
- a socket element, a plug-in element, and a locking element, wherein the socket element has a tube-like receiving region for receiving the plug-in element, wherein the locking element has a securing element which is supported in a plugging-in direction against a securing mating element of the plug-in element and the locking element is supported with a locking device against a locking mating device on the socket element, such that the socket element and the plug-in element are secured axially indirectly via the locking element and thus via the securing element, the securing mating element and the locking device and the locking mating device;
- wherein the securing element is configured as a front edge of a locking tongue, wherein the locking tongue extends with a free end in the plugging-in direction, wherein the free end includes a radially outwardly protruding flange portion with an axial front side with a chamfer, wherein the chamfer extends axially to a tip of the free end.
