Meaning of Zapriski Fang

Question

Back in the seventies (before the revolution) I worked in Iran and one of my contacts was a radiographer who was partly Russian. He had the habit of shouting "Zapriski Fang" as an indication of surprise, anger or pleasure. He refused to tell us what it meant ("It's Russian" was all he would say). Of course my transliteration and/or 40-year memory may be incorrect. The local language was Farsi and we used English for mutual communication.

I have long wondered what it meant and today I googled/duckduckgoed it (go ahead, I saw nothing dangerous). I got zero meaningful text results but loads of images where I can see no pattern whatever.

So, what is (or was) Zapriski Fang? And what are all the images?

Edit: the pronunciation was roughly to rhyme with "a whisky bang" or "the frisky gang", with the stress on the second syllable. Other staff (doctors, nurses) would have heard him and did not react, so it is unlikely to have been a Farsi or local-dialect obscenity.

Answer 1

As @MikeHas noted, this is probably

Запри скафандр - Zapri scaphan[dre] - Lock (your) space-suit up

But I doubt if that could have some relation to Heinlein or such. For me, it sounds just like a very rare saying of surprise (so rare, I admit I never heard this one before).

Answer 2

As far as at that time it was not so typical to use obscene language in public,and, on the other hand, we can use any phrase deprived of its lexical meaning as an euphemism to show surprise, anger or pleasuse, it can be whatever you want. I like the version with "Запри скафандр" by @Mike Has, but we can't say for sure.

My grandmother used "Забодай тебя комар!", which means "Let a mosquito gore you".

We can say "японский городовой!", "твою дивизию!", and many other semi-decent phrases implying a more swearing phrase, as they are parallel in construction and have sound similarities with it.

But folk non-obscene expressive phrases like "забодай [тебя] комар" can be used even in a group where children are present.
