Of all the enormous selection of connections from PC sockets to flashes, none is more reliable than the "household" connection. The household connection never seems to accidentally disconnect and cause you to miss a shot, which will very likely happen at least once with any other type of connection.
Instead of having multiple different PC cord types for all of your different flashes, convert all of your various flash connections to the household standard by employing this device and just a single household to pc male cord.
The Wein HSH adapter has a hot shoe connections on top and a "cold" shoe upon the bottom, as well as a threaded 1/4"-20 socket so that you can attach the device to any 1/4"-20 threaded screw if you desire. The HSH provides a "H" household socket on the side of the adapter that allows you to connect accessories with a household type plug.
As the Wein deliberately fits the flash's foot extremely tightly, this device is not intended for daily use with mutli-pin TTL flashes. It is okay to use with TTL flashes from time to time; just be careful and deliberate when attaching and removing the flash from this shoe. The benefit to these narrow tolerances is absolute reliability.
