Earlier in the week, the South Africans contested the Centrale Sevens in Paris, where they won the tournament by beating Ukraine in the final.
In Stade Matter de Nancy on Sunday, they outplayed Switzerland 46-0 in the Cup quarter-finals and then beat Poland 17-12 to set up the final against Sweden.
The final was a tight affair in the first half, with the Swedes having most of the possession, but they were unable to break down the South African defence. The limited attacking opportunities by the Springbok Women's Sevens side were thwarted with handling errors and at the break, both teams were still scoreless.
The second half saw a much better effort from South Africa. Mathrin Simmers broke the duck after good interplay with Nadine Roos before with Rights Mkhari rounded off a regular training pitch move to dot down. Simmers then got a second straight from the kick-off, before Roos scored near the posts and converted her own try.
Springbok Women's Sevens coach, Paul Delport, said their defensive effort was crucial in the first half.
"Sweden were really good in that first half," Delport said.
"They held onto the ball for long periods and if it was not for our brave defensive effort, things could easily have gone wrong for us.
"The win is magic for the squad, it was a proper experiment for us, playing two tournaments in such a short time. We needed to be tested and we were. They came through this so well, we have no major injuries. We wanted to start get a winning culture going and this will do a lot for our self-belief."
Delport said the variety of opponents was a good things: “We had some easier games, but we were tested by the likes of Ukraine, Poland and Sweden and that was what this tour was about. We are taking a lot of positives back home."
Delport applauded the squad for their "massive effort".
"We moved players around and asked a lot of them. I am very proud of what we did. We were tested mentally and physically. Our management deserves praise for that. We would love to be back," he said.
• Nadine Roos was named Player of the Tournament in both the Centrale Sevens and Stanislas Sevens. The squad arrive back in South Africa on Tuesday.
