A disposable cervical cap has a thin form-assuming pliable, dome with an integrally-molded resilient retaining rim. The rim has a bevelled outer shoulder and contains an annular groove on its inner surface. The inner groove and rim define two ascending lips on the inner surface of the rim which prevent dislodgement of the cap from the cervix. The cervical cap includes a set of tabs on its outer surface to assist in positioning and placement of the cap and further includes a loop for removing the cap after use.
