A fiber optic connector has a plug region at a first axial end and an anchor region at a second axial end. The anchor region includes first interlock members which protrude outwardly from a support portion. A crimp sleeve can be disposed over the anchor region of the plug connector so that a surrounding portion (e.g., a jacket and/or strength members) of the cable extends between the crimp sleeve and the first interlock members. When the plug connector is assembled, second interlock members can be formed in the crimp sleeve to extend radially into gaps between the first interlock members to enhance retention of the surrounding portion of the cable therebetween.
