A connector assembly that has a connector including a coupling member rotatably coupled to a body, a gripping sleeve that receives a portion of the body and a portion of the coupling member, and a torque limiting feature associated with both the gripping sleeve and the coupling member. The torque limiting feature has first and second predetermined torque limits. Rotation of the gripping sleeve applies torque to and rotates the coupling member in a tightening direction until the first predetermined torque limit is reached such that no additional torque is applied to the coupling member by the gripping sleeve that is greater than the first predetermined torque limit. The gripping sleeve rotates with respect to coupling member in a loosening direction until the second predetermined torque limit is reached thereby allowing the gripping sleeve to rotate the coupling member in the loosening direction.
