  • Patent number: 9528647
    Abstract: A coupling for connection to a source of fluid pressure such as in a breathing-protection. The coupling has a socket end and a plug end insertable into the socket end. The socket end has a body and a locking sleeve on the body. As the plug end is inserted into the socket end, the locking sleeve is moved axial from a first axial position to a second axial position locking the plug end within the socket end, and rotationally from a release position to a locked position delimiting the movement of the locking sleeve from the second axial position to the first axial position. When the coupling is pressurized, a piston within the body is moved from a retracted position to an extended position delimiting the rotational movement of the locking sleeve from the locked position to the release position.

  • Patent number: 8596689
    Abstract: A short-body connector for fluid couplings made of a sleeve-shaped body. In the sleeve-shaped body an internal thread is provided, by which the connector can be screwed onto a threaded connection. Relative to axial extension, the locking groove and locking rib serving to hold the connector in the coupler are located at the height of the thread. That is, the locking rib and locking groove located ahead of the thread in the state of the art have moved to the region of the thread in the arrangement according to the invention.
