Extension Cord Plug Separation Keeper
A 130 x 44 x 6 mm plate that keeps an extension cord and a tool cord from pulling apart at the plug. You push a loop of each cord through an 11 x 26 mm slot and hook it over the notched end. The slots take two passes of cord up to about 10 mm across (16 AWG to 12 AWG SJTW), so a tug on either cord pulls on the plate and not on the joined plugs.
