1. A coupling device for sealingly connecting the adjacent ends of axially aligned members in end-to-end relation, comprising:

  • a. a coupling structure having two cylindrical parts threadedly connected at adjacent ends and upon relative rotation being axially contractible, the other ends of said parts being adapted to respectively surround the members to be coupled;

    b. sealing means for peripherally sealing the adjacent ends of the coupled members and said coupling structure in response to the axial contraction of said coupling structure; and

    c. detent means interconnecting the threadedly connected ends of said parts, said detent means having resiliently engaged elements coacting to yieldably oppose relative rotational movement of said connected parts at spaced dwell points, and at each dwell point yieldably restraining relative movement of the parts therefrom in opposite directions.
