A trailer hitch assembly sized and shaped to fit within a trailer hitch receptacle, wherein the trailer hitch assembly includes a first tubular element and a second tubular element. Each tubular element has an angled end, wherein the angled ends of the first tubular element and the second tubular element are complementary to each other. The trailer hitch assembly may further include at least one guide to assist in aligning the first tubular element with the second tubular element along the angled ends. The trailer hitch assembly may further include an actuator configured to engage both the first tubular element and the second tubular element and to diagonally displace the first tubular element relative to the second tubular element.
