QUICK-RELEASE FASTENER
A quick-release fastener for connecting automobile pipes includes, but is not limited to a base body having a partially circular cross-section. At least one first rib projects radially inward from the base body to form an anti-rotation element. Furthermore, at least one second rib projects radially inward from the base body to form an anti-rotation element, and the first rib is arranged axially at a distance from the second rib. Due to the quick-release fastener, a fast and simple connection of automobile pipes is possible even with confined installation space.
1 . A quick-release fastener for connecting pipes of an automobile, comprising:
a base body having a partially circular cross-section;
a first rib that projects radially inward from the base body to form an anti-rotation element; and
a second rib that projects radially inward from the base body to form a second anti-rotation element,
wherein the first rib is arranged axially at a distance from the second rib.
2 . The quick-release fastener according to claim 1 , wherein the base body has two axially extending longitudinal edges and the two axially extending longitudinal edges have a second distance, which is selected in such a manner that the base body may be placed resiliently onto a pipe piece whose nominal diameter substantially corresponds to an inside diameter of the base body.
3 . The quick-release fastener according to claim 1 , wherein at least one of the first rib or the second rib have a radially inwardly pointing support edge that corresponds to a secant of the base body.
4 . The quick-release fastener according to claim 1 , further comprising a third rib arranged radially opposite to the first rib.
5 . The quick-release fastener according to claim 1 , wherein the base body has two front-side front edges adjoined by at least one of the first rib or the second rib.
6 . A pipe connection for an automobile, comprising:
a first automobile pipe having a first undercut with a first contouring to form an anti-rotation element;
a second automobile pipe having a second undercut with a second contouring to form a second anti-rotation element; and
a quick-release fastener comprising:
a base body having a partially circular cross-section;
a first rib that engages the first undercut to form the anti-rotation element; and
a second rib that engages the second undercut to form the second anti-rotation element.
7 . The pipe connection according to claim 6 , further comprising a pipe connecting piece that tapers in a distal direction for axial insertion into the quick-release fastener and the distal direction relative to at least one of the first undercut or to the second undercut.
8 . The pipe connection according to claim 6 , wherein the first automobile pipe has a pipe projection for insertion into at least one of the second automobile pipe or the second automobile pipe and has a second pipe projection for insertion into the first automobile pipe.
9 . The pipe connection according to claim 8 , wherein the pipe projection comprises a seal.
10 . The pipe connection according to claim 6 , wherein the pipe connection is disposed in an engine compartment of the automobile and adapted to pass charged fresh air for at least one of an internal combustion engine, air for air conditioning systems or cooling water.
