ABSTRACT A locking terminal assembly is provided in combination with a hermetic motor compressor having an outer housing with a motor and compressor in the outer housing, and three terminal pins secured in the outer housing for supplying electric current to the lead wires of the motor. The locking terminal assembly comprises a pin housing having three cavities therein, each cavity having a locking means on its inner surface, and three holes therein perpendicularly aligned with respective ones of the cavities for receiving respective terminal pins therein. Connector clips are provided to be attached to the lead wires and have resilient tabs for removably securing each connector clip in a respective cavity when the tabs engage the locking means therein. A pin-receiving opening is provided with each connector clip, and upon receiving the connector clip in a respective cavity, the pin-receiving opening is aligned with the respective hole. The pin-receiving opening is provided with a knurled inner surface which frictionally retains a terminal pin received in the pin-receiving opening. The knurled surface provides a secure elec- trical connection between the terminal pins and the motor lead wires during assembly and shipment of the compressor, while minimizing the reduction in electrical surface contact between the terminal pin and connector clip .
