  • Patent number: 6102448
    Abstract: An arrangement for connecting two pipe ends comprising a respective closure part around each of the pipe ends. The closure parts are connected together in a bayonet-type connection. One closure part includes an annular surface with a first part parallel to a sealing device placed between the pipe ends and with a second part inclined with respect to the sealing device. The latter part draws the closure parts and the pipe ends together as the closure parts are rotated relatively toward each other and as the one closure part is guided along the inclined portion of the annular surface. A respective sealing surface is provided on each of the pipe end parts. The sealing surfaces are brought axially toward each other by movement together of the closure parts.
