1. A connector for selective attachment to the exterior of an elongated member of circular cross-section, said connector comprising:

  • a. An attachment fitting having formed therethrough a bore sized to slidably receive a portion of the length of the elongated member;

    b. a compression recess formed in said attachment fitting having opposed first and second ends, said bore communicating with said first end of said compression recess and being disposed in coaxial alignment therewith, said compression recess between said first and second ends thereof having sidewalls enlarged radially relative to said bore and configured to encircle a portion of the length of the elongated member distinct from the portion thereof received in the bore;

    c. a resilient, annular gripping member housed in said compression recess and configured to encircle the portion of the elongated member therein;

    d. a locking hub configured for encircling the elongated member at said second end of said compression recess and having a compression face projecting into said compression recess from said second end thereof, said locking hub being movable longitudinally relative said attachment fitting between a disengaged position in which the elongated member is slidable relative to said gripping member and an engaged position in which said compression face bears against and deforms said gripping member to preclude sliding of the elongated member relative said gripping member by urging said gripping member into radial engagement with the portion of the elongated member in said compression recess; and

    e. cooperating means located on opposing portions of said attachment fitting and said locking hub for selectively locking said locking hub in said engaged position thereof, and wherein said cooperating means comprises a retention pin and a retention slot configured to receive said retention pin in said engaged position of said locking hub, said retention pin entering said retention slot due to relative movement between said locking hub and said attachment fitting as said locking hub moves from said disengaged to said engaged position thereof.
