1. In a structural system including an attaching component provided with at least one connecting port, a structural component, and a coupling mechanism adapted to attach said structural component to said connecting port of said attaching component;

  • an improved coupling mechanism comprising;

    an elongated jaw assembly disposed coaxially within said structural component proximate an end thereof and movable between an extended and a retracted position, said jaw assembly including a plurality of radially expansible jaws adapted to engage an inner perimeter of said connecting port when they are extended out of said end of said structural component to said extended position;

    an elongated locking pin disposed coaxially within said jaw assembly, said locking pin being movable between a locked and unlocked position, where moving said locking pin from said unlocked position to said locked position causes said jaw assembly to move from said retracted to said extended position, and where moving said locking pin from said locked position to said unlocked position causes said jaw assembly to move from said extended position to said retracted position;

    an operating sleeve disposed around said end of said structural component; and

    means connecting said operating sleeve to said locking pin such that movement of said operating sleeve causes a corresponding movement of said locking pin.
