A safety back-up sensor, formed with a cylindrical jacket with two ends and a hollow core between the two ends to accommodate a rubber bushing and a signal sensor module. Multiple parallel longitudinal resilient tabs are formed on the cylindrical jacket. The resilient tabs protrude from the exterior surface of the cylindrical jacket and have transverse teeth to prevent the senor body from being dislodged. Longitudinal ribs are formed on alternate resilient tabs to prevent the sensor body from rotating. With these specially designed transverse teeth and ribs, the sensor is able to counter the external rotating and shifting forces present in various driving conditions and to firmly affix the sensor to a vehicle bumper.
