Slightly less risqué way to say "cock ring." Device that fits around penis and/or testicles and has a semi-tourniquet function to hold erections longer.
"Some drugstore. Where the hell do they keep the cock rings?"

"Where the hell do they keep the erection rings?"

"Hell if I know. Try 'Adult Pleasures' or 'Family Planning.'"
