ABSTRACT:
A condom retainer ring structure is for use on a condom that has an elongated thin-walled tubular sheath of resilient material closed at one end and open at the other end, with a bead surrounding the opening. The condom retainer ring structure has a first ring for positioning at the periphery of the opening, adjacent the bead that surrounds the sheath. A second ring is connected to and adjacent the first ring. A bridge having a retention notch therein joins the rings generally in a single plane when the retainer ring structure is not in use and in an unflexed condition. In use, when a condom is worn on the penis of a user, the first ring surrounds the sheath on the shaft of the penis, the second ring encircles the scrotum to anchor the condom, and the bridge is flexed thereby, constricting the retention notch. The retention notch, preferably positioned over the bead of the condom, grabs the bead to retain the condom.
