An intra-uterine contraceptive device comprising a longitudinally rigid, transversely resiliently compressible body having each of its longitudinal ends expansible upon compression of the other; means limiting the expansion of one of its ends formed of a resiliently pliable material molded on said body at said end and along its side edges; the resiliently pliable material projecting beyond said body at said end to provide a compressible, longitudinally deformable extension of said body. The limiting means and the extension include a diaphragm across the width of the body; the diaphragm defined by thickened ribs along its free edge portions.
