Dubbed the "rape trap", trademarked "Rapex", the condom-like device bristling with internal hooks designed to snare rapists has re-ignited controversy over South Africa's alarming rape rate, even before plans for its production were announced in Western Cape this week.
Some say the inventor, Sonette Ehlers, a former medical technician, deserves a medal, others that she needs help.
The device, concealed inside a woman's body, hooks onto a rapist during penetration and must be surgically removed.
Ms Ehlers said the rape trap would be so painful for a rapist that it would disable him immediately, enabling his victim to escape; but would cause no long-term physical damage and could not injure the woman.
Some women's activists call the device regressive, putting the onus on women to address a male problem.
Charlene Smith, an anti-rape campaigner, said it "goes back to the concept of chastity belts" and would incite injured rapists to kill their victims.
