摘要： A ring that locks to a condoms elastic band that is put on the penis before the condom so the condom can have its elastic band pulled into a groove along the center of the ring. It has two sides that slide open and shut over the top of the condoms elastic band to lock it in place on the ring. The ring is shaped wider then the hole of the vagina so it hooks onto the outer area of the vagina so that the condom cannot slide off during sex even if there is lubrication inside the condom.
