1. A device for selectively coupling and/or decoupling a plurality of pipe sections, comprising, in combination:

  • a plurality of hollow members each having a tapered inner surface portion and adapted to receive at least one of said pipe sections;

    a plurality of spherical bodies disposed between said tapered inner surface portion of a hollow member and a portion of the outer surface of an associated pipe section for acting as wedge means to prevent separation of said hollow member from said associated pipe sections;

    sealing means disposed between a hollow member and its associated pipe section for selectively providing an air-tight seal therebetween when said sealing means is compressed;

    fastening means disposed between said hollow members for moving said hollow members toward each other and for urging said sealing means against the inner surface of said hollow members and the outer surface of said pipe sections;

    said hollow members comprise cylindrical members which are disposed in axial alignment in a spaced relation;

    said spherical bodies are disposed in abutment against said tapered inner surface portions and said pipe sections for acting as wedge means to prevent said pipe sections from coming off of said cylindrical members;

    said sealing means includes resilient elements disposed between said cylindrical members and said pipe sections for providing air-tight seals between said cylindrical members and said pipe sections;

    said fastening means is disposed between said cylindrical members for pulling said cylindrical members toward each other so as to urge said sealing means against the inner surface of said cylindrical members and the outer surface of said pipe sections; and

    wherein said air-tight sealing means comprises resilient retainer rings each having a plurality of said spherical bodies partially embedded therein, resilient stop rings in abutment against said retainer rings, and resilient packing members in abutment against said stop rings on the side opposite to said retainer rings.
