A lamp holder connector adapted for connecting with a lamp includes a first holder, a second holder, a connecting part, at least two buckling ears, a first terminal assembled in the first holder and a second terminal assembled in the second holder to electrically connect with the first terminal. Two opposite sides of the first holder defines two restraining arms. The second holder defines an accommodating chamber for receiving the connecting part therein. The connecting part defines an accommodating space for receiving the first holder therein. The two buckling ears are pivotally fastened to two sides of the connecting part. Two tops of the two buckling ears are matched with the restraining arms. Each buckling ear has at least one propping portion projecting into the accommodating space to prop up the first holder under rotating actions of the buckling ears when the lamp holder connector is disassembled.
