Abstract: A plug connector (11, 12, FIG. 1) has insulators (16,26) that hold male or female contacts (13, 14, FIG. 3) received in boreholes (19, 29, FIGS. 4A, 4B)). A rear insulator holds a male or female contact (13, 14), which receives cables (45, 55, FIG. 3). The boreholes (19, 29) form fingers (78, 98, FIGS. 4A and 6) that can be radially spread apart to detachably hold the connector contacts (13, 14) in a preliminary locking manner. The plug connector also has a front insert (60, 80) with a front borehole (65, 85) aligned with the rear boreholes (19, 29) and being able to be placed in a non-detachable preliminary locking position that makes possible the attachment of the connector contacts (13, 14) and in a final locking position that holds the connector contacts (13, 14) in a non-releasable fashion.

Abstract: A clip unit (10) that holds an electrical contact (11) in a passageway (12) of a connector frame (13), is of small cost and small length and can be installed using a small force, and provides the functions of centering a location along the contact within the passageway and preventing rearward movement of the contact along the passageway. The unit includes front and rear ring-shaped clip elements (25, 35) that each has a slot (26, 36) that is expanded to mount the unit in a neck (18) of the contact. A contact with the unit installed is pushed forwardly along the passageway until the front clip element encounters a constriction (45) in the passageway which compresses the diameter of the front clip element until it moves forward of the constriction and then expands. Thereafter, a rear end (27) of the front element abuts the constriction while a front end of the front element abuts a collar (17) of the contact to prevent rearward movement of the contact.
