Need ID Sci-fi horror type movie late 70’s or early 80’s

I cannot figure out what this movie was. The only scene I remember was a man and a woman each dressed in futuristic outfits walking carefully through a metal tunnel. The suits were like futuristic flight suits. The Inside of the tunnel was like flexible electrical conduit except maybe 8’-9’ diameter.

The woman is walking in front and sets off a trap that causes a metal cable to spring from one of the inside rings of the tunnel. It instantly snags one of her legs by the calf or ankle and has her trapped on the floor of the tunnel. She tells the man to go on without her. When he returns later, her body has been cut into mush by other tight metal cables.

Basically every ring of the tunnel was rigged with extremely high tension cable traps.
