Abstract: A connector (e.g. coaxial connector) comprises a tubular body structure (22, 23) with an axially extending bore therein for receiving an incoming cable (40) (e.g. coaxial) and for accommodating electrically-conductive contact-making means (31) located adjacent a part of the cable within the tubular body structure and electrically coupled with contact means (32) (e.g. pin contact) of the connector. Axially displaceable means (35) at least partly received by the tubular body structure (22, 23) causes the contact-making means (31) to make good electrical contact with a conductor (44) of the cable (40) (e.g. control conductor of coaxial cable) in response to a predetermined axial displacement of the displaceable means (35). The displaceable means (35) has a first positive hold position relative to the tubular body structure in which position the displaceable means acts solely to retain other connector components within the tubular body structure (22, 23).
