Abstract: In an embodiment, a coaxial quick connector assembly comprises an inner connector body having a first end for coupling with a coaxial cable and a second end having a perimeter contact for engagement with an externally threaded coaxial coupling. The perimeter contact includes a wall defining a central passageway. The perimeter wall includes at least one protrusion projecting toward the central passageway. An outer connector body is in mechanical communication with the inner connector body such that when the perimeter contact is engaged with the externally threaded coaxial coupling and the outer connector body is moved to an engaged position, an interior surface of the outer connector impinges the at least one protrusion between the interior surface of the outer connector body and the external surface of the externally threaded coaxial coupling, such that the assembly is held in place with respect to the threaded coaxial coupling.
