A connector assembly includes a pin connector for receipt by a box connector. An external surface of the pin features a helical groove; a generally complementary internal surface of the box features a helical groove of the same rotational sense and pitch. A helical latch coil is carried in one of the grooves, extending partly out of the groove. The connectors are latched together by stabbing the pin into the box, whereby the latch coil is ratcheted into place, partly extending into the groove of the connector not carrying the coil. Subsequent mutual rotation between the connectors in one rotational sense tightens the latched connection; rotation in the opposite sense releases the latching. |
