that looked like the hook side of a velcro zipper. [If you buy a new OEM one, it will also have the piece of plastic on it.] They whould just jam it in until it bottomed out. The plastic would break away when the wheel started rotating and everything was fine. The sensor is just a magnetic trigger switch that is activated by the "teeth" in the rotator pressed on to the respective drive-shaft. Make sure you put the sensor in the same position [in relation to the wire coming out of it} as it was before replacement. It will work in any position as long as no magnetic metal attaches itself to the the head of the sensor. If not in the correct position the magnetic pulse is weaker and it may not open and close the circuit. Some scanners will let you know if the pulse is not there from each wheel while your driving the vehicle
