Abstract: A coupler for rigidly connecting two cables in series in series is provided. The coupler includes a first component that includes a receiving volume that extends from a first end face of the first coupler. The receiving volume extends through a side surface of a body of the first component through an aperture. A second component is slidably engagable with the first coupler. The second component includes a finger that extends within the receiving volume, the finger includes a second portion that extends through the aperture. The second component can engage the first component with in a direction parallel to the longitudinal axis of the first component as well as in a direction perpendicular to the longitudinal axis of the first component.
