A plug includes a body having a longitudinal axis, a prong extending outward from the body parallel to the longitudinal axis, and a biasing element within the body applying lateral pressure to the prong. A second prong can be provided that extends outward from the body parallel to the first prong, and the biasing element can apply lateral pressure to the second prong. The first prong can be biased toward or away from the second prong, and both can be biased in opposite directions. The biasing element can include a spring, and the spring can be disposed between the first prong and the second prong. Also, the biasing element can cause the prong to angle toward or away from the longitudinal axis. A locking mechanism can be provided to move or inhibit movement of the first prong and the second prong.
