The invention provides a star-shaped self-locking connector. The connector comprises a first pipe body and a second pipe body, wherein a plurality of first protrusions arranged along the circumferenceof the first pipe body are arranged on the end surface of one end of the first pipe body, a first notch is formed between every two adjacent first protrusions, a plurality of first limiting ribs arranged in a parallel mode at intervals are arranged on the two first inner side wall surfaces of each first protrusion correspondingly, a plurality of second protrusions arranged along the circumferenceof the second pipe body are arranged on the end surface of one end of the second pipe body, a second notch is formed between every two adjacent second protrusions, and a plurality of second limitingribs arranged in a parallel mode at intervals are arranged on two second inner side wall surfaces of each second protrusion correspondingly. When the second pipe body is connected with the first pipebody, self-locking is achiev
