Sometimes I hate KAS

[Roskerbos]

In this case, I suspect it's the pipe end-point, which seems capable of spontaneously exploding when left unattended.

When combined with KSP's shonky "Physics" you get random Guy Fawks moments when you least expect them. It's bad enough that a Kerbal, turning abruptly, under a lander can send it flying skywards, but this is ridiculous.

Hours and hours of work wrecked.

Weird I have never had any issues like this.

Yes then connecting an small probe to an fuel station it might start to move. also connecting two large ships in orbit. you should always turn of sas.

SAS was on the mining rig, to hold it steady while drilling. The rig was one of the parts which wasn't affected.

Try switching to it with gravity already hacked in the debug menu, and with no crash damage etc selected. It will probably just go flying off into space, but it might behave differently. Even if it does go flying off, as long as it doesn't explode, you could just hyperedit it back to its location and then disconnect the pipes.
