Technical Examples

A plug retention apparatus for use in securing two plug members together to prevent undesired disengagement. The plug retention apparatus is affixed to a first plug member using a retention ring which provides a means for adjustable positioning via a threaded coupling to facilitate securing a second plug member to the first plug member. A plug clamp may be rotatably positioned about the second plug member retaining the plug members in a desired position. The plug retention apparatus may include a sleeve removably disposed about the cord of the first plug. The clamp used for retaining the second plug may include a cord support, a latch to secure the cord on the support and a locking mechanism to selectively retain the latch in a closed position.
