The utility model discloses a quick-assembly pipe clamp, which comprises a pipe clamp body. The quick-assembly pipe clamp is characterized in that the pipe clamp is an elastic ring with two ends provided with barbs, the elastic ring is sleeved in a pipe body required to be clamped, the head of the pipe clamp is inserted into a mounting hole of a support, and a bolt is fixed onto a machine body or wall body after penetrating through the mounting hole of the support. As the pipe clamp has fine elasticity and is opened in a natural state, the pipe clamp clamped in the hole of the support fixes parts (such as a rubber pipe) by aid of self elasticity after being assembled. Besides, the pipe clamp assembly structure comprises the pipe clamp, the support and the bolt. The quick-assembly pipe clamp has the advantages of simple structure, convenient mounting and dismounting, low cost and the like.
