Abstract: A self-locking connector for pivotably interconnecting a carburetor throttle valve member to a cable connected vehicle accelerator pedal member includes a nailhead-like pin projecting from the one member for insertion through a keyhole slot in the other member, the other member having a movable retainer/cover normally biased to a position overlying the slot prior to assembly of the two members, the retainer/cover being retractable to uncover the slot and permit passage of the pinhead through the slot, return movement of the retainer/cover engaging the ends of the retainer/cover with the pinhead moving it into the smaller diameter portion of the keyhole slot and engaging the end of the retainer/cover under the head of the pin preventing withdrawal of the pin from the slot and locking the two members pivotably together.
