The invention relates to a slack-preventing connector comprising a connector casing. A connecting screw cap is assembled outside the connecting casing; a slack-preventing mechanism for preventing the connecting screw cap from reversing and slacking is arranged between the connecting screw cap and the connector casing and comprises a doubling-up jump ring, an elastic ratchet ring and a baffle which are pressed between the connecting screw cap and the connector casing along the axial line in sequence; the doubling-up jump ring is in interference passing installation with the connector casing and is in check swing fit with the elastic ratchet ring; an outer ring of the elastic ratchet ring is integrally provided with an elastic cantilever extending along the circumferential direction; convexteeth protruding outwards along the radial direction are arranged at the tail end of the elastic cantilever; the connecting screw cap is internally provided with ratchets which are correspondingly and unidirectionally meshed with the convex teeth; a circular bead is arranged on the outer circumferential surface of the connector casing; an annular table is arranged on the inner circumferential surface of the connecting screw cap; and an anti-backlash spring is pressed between the annular table and the circular bead. The connector can effectively prevent slack and is applicable for environmentswith vibration.
