The utility model discloses a protective net rapid to connect. The protective net comprises protective net bodies. T-shaped clamp strips and T-shaped clamping grooves are arranged on two sides of each protective net body. The T-shaped clamp strips are matched with the T-shaped hollow clamping grooves in shape. The boundary dimension of each T-shaped clamp strip is smaller than inside diameter dimension of each T-shaped clamping groove. The T-shaped clamp strip between every two protective net bodies is mounted in the corresponding T-shaped clamping groove. Through holes corresponding in position are formed in the T-shaped clamp strips and the T-shaped clamping grooves. Bolts for fixing the T-shaped clamp strips and the T-shaped clamping grooves are arranged at the through holes. According to the protective net, each protective net body is provided with the T-shaped clamp strips and the T-shaped clamping grooves on two sides, and the two adjacent protective net bodies can be connected with each other rapidly and are fastened through the bolts, so that shedding of the protective net bodies after clamping can be prevented. The protective net has the advantages of small size, convenience in transport and capability of saving construction cost and the like.
