Bajonett Adapter

We do own a Dorema Air tent which comes with a manual pump. However we're still too lazy during camp site to inflate it manually. therefore I did buy a spinera pump which works great. Unfortunately the hose is a bit too short.

This made me design an adapter to connect the hose of the spinera pump with the hose to connect against the manual pump. This now makes it easy to inflate the top air buffers without holding up the pump.

It's the 4th version which now connects quite ok. Maybe I'm going to improve it later on depending on the experience of how it does its job.

/edit: Durjng our hols I started a first test under real conditions. It did fit however it was not exactly tight enough. It leaked a bit of air, so my spinera did not recognize the target pressure. So this does need a bit more investigation.
