    Abstract: A power cord connection device that reinforces the plug-to-plug connection between two power cords. The shaped main body of the invention is fitted with an attachment rope that is fastened behind the plug of a primary power cord. A secondary power cord is plugged in and makes a wide loop between the end of the main body and the plug-to-plug connection, while the attachment rope is taut under direct tension over the same distance. The secondary power cord is then looped through the openings and over the friction ridges of the main body. Any strain upon the primary power cord now bypasses the plug-to-plug connection in favor of the attachment rope. The invention also transfers the hanging weight of an extension cord to a ladder. The invention also keeps a power cord organized for storage.
