1. An apparatus for connecting an elastic hose to a system comprising:

  • a. a hollow body having an inner surface and a central axis;

    b. a stem, a portion of which serves as a means for connecting said body to a system;

    c. a barb having a conically-shaped surface, a base terminating said conically-shaped surface, and an outer periphery formed at the intersection of the base and the conically-shaped surface said outer periphery having a circumferential length along which said hose seals to the system and which also holds said hose in the direction of the central axis, said barb being integral to the body and being disposed so as to engage the inner surface of said elastic hose; and

    d. a means for resisting rotation of said hose about said body, wherein said means is located only on said outer periphery of said barb, and is disposed so as to engage the inner surface of said elastic hose, and wherein said means for resisting rotation smoothly deforms the inner surface of said elastic hose along said outer periphery such that the circumferential length of said outer periphery forms a smoothly curved non-circular line.
