A female condom with jagged "teeth" that grips a man's penis is the latest device developed to catch rapists in South Africa, CNN reported Sunday.

South African Dr. Sonnet Ehlers is distributing the condom — called Rape-aXe — for free during the World Cup, in a country with one of the worst rape rates in the world.

The condom is inserted by women like a tampon and its jagged teeth-like hooks inside attach to a man's penis during intercourse.

Once it grabs hold, only a doctor can remove it. Ehlers hoped this will help authorities to catch offenders.

"It hurts, he cannot pee and walk when it's on," Ehlers said.

"If he tries to remove it, it will clasp even tighter... however, it doesn't break the skin, and there's no danger of fluid exposure."

During the World Cup she plans to distribute 30,000 of the free devices. After the trial period they will be sold for $2 each.

"The ideal situation would be for a woman to wear this when she's going out on some kind of blind date ... or to an area she's not comfortable with," Ehlers said.

Critics suggest the condom puts women at risk of further violence from men trapped by the device and reminded women of their vulnerability.

Others accuse her of inventing a medieval device.

"Yes, my device may be a medieval, but it's for a medieval deed that has been around for decades," Ehlers said. "I believe something's got to be done... and this will make some men rethink before they assault a woman."
