Cable locking device

A cable locking device adapted for the connection of a first electrical wire to a second electrical wire, comprising:

• a first part having a longitudinal axis and a first cavity for receiving the first electrical wire and a projection extending longitudinally from an opposite end relative to the first cavity, the projection forming a tapered convex surface symmetrical about the longitudinal axis of the first part;
• a second part having a longitudinal axis and a first cavity for receiving the second electrical wire and a second cavity on the opposite longitudinal side of the first cavity having an opening that receives the projection of the first part, the second cavity having a tapered concave surface longitudinally opposite the opening and symmetrical about a longitudinal axis of the second part and corresponding in curvature to the tapered convex surface of the projection of the first part;
• a first channel formed on an inner sidewall of the of the first cavity and extending longitudinally from the opening of the second cavity and formed within the second cavity of the second part;
• a second channel formed on the inner sidewall within the second cavity of the second part, the second channel connected to the first channel and extending in a circumferential transverse direction of the first channel, wherein the first and second channel are radially enclosed and include a radially inwardly facing surface;
• a pin extending radially outward from the projection of the first part, wherein the pin fits within the first channel such that the projection and pin slide longitudinally into the second cavity with the pin sliding through the first channel, and wherein the pin fits within the second channel such that the pin travels within the second channel when the first part is twisted about the longitudinal axis after the projection and pin are inserted into the second cavity;
• and
• wherein the pin frictionally engages the second channel so as to frictionally hold into place the pin with respect to the second channel so as to connect the first part to the second part;
• wherein as the pin travels down the second channel from the first channel to an of travel in the second channel, sidewalls of the second channel engage the pin and prevents inadvertent disconnecting of the first part from the second part;
• wherein the pin is frictionally engaged at the end of travel;
• wherein disengagement of the pin from the end of travel from second channel toward the first channel requires a greater force than the initial frictional engagement.
