Retrieval device with locking feature

A device for locking a cable to prevent it from sliding, comprising:

• a control cable with a first end and a second end, and with a main axis along its length;
• a body;
• a rocker arm pin having a loop on a first end, the loop configured to receive the control cable through its center, the rocker arm pin with a second end that connects to the body, the first end of the rocker arm pin configured to rotate around the second end of the rocker arm pin on an axis orthogonal to the main axis of the control cable from an unlocked position wherein the plane of the loop is substantially orthogonal to the main axis of the control cable to a locked position wherein the plane of the loop is substantially parallel to the main axis of the control cable;
• a first spring having a first spring end connected to the first end of the control cable and a second spring end connected to an object;
• the loop on the rocker arm pin configured to remain in the unlocked position when a pull force is applied to the second end of the control cable wherein the second end of the control cable is on an opposite side of the loop on the rocker arm pin from the first end of the control cable and the control cable moves in a backward direction through the loop, and the loop configured to move to the locked position when the pull force is withdrawn and the first spring pulls the control cable in a forward direction through the loop and the loop configured to pinch the control cable against the body in the closed position.
