"Double ended male 'adapters" are illegal, dangerous, a fire hazard,

Naive question: does anyone even make those evil things? (I mean
commercially, not homemade.)

Patent Applied For

"A double male electrical connector is provided to connect the female end of
a string of Christmas lights with the female end of an extension cord
suitable for plugging into a wall outlet. The inventive connector is
particularly useful when Christmas lights are wrapped from the wrong
direction so that after wrapping the lights the female end is loose. The
connector includes a conventional conductive cord with a first end and a
second end. The first end has a first male plug and the second end has a
second male plug. Each male plug has a first lead and a second lead for
plugging into a two-prong receptacle. In accordance with the invention there
is no third grounding lead. In an alternative embodiment the connector has a
safety cap on at least one of the male plugs for safety, i.e., when the
connector is not in use. In the preferred embodiment the apparatus includes
a jacket receiving the connector for axially slidable use so that both male
plugs cannot both be simultaneously exposed."
