ABSTRACT:
A joint structure for connecting a corrugated pipe to a fixed part includes a main body, a packing screw cap, and a clamping claw. The clamping claw is sandwiched between the main body and the packing screw cap. The clamping claw defines a through slot at an edge thereof to make the clamping claw can enlarge an inside diameter thereof. A plurality of inner claws is formed at the edge of the clamping claw. A locking part protruding towards the center of the clamping claw is formed at an end of each of the inner claws. Two slits are respectively defined at two sides of each inner claw so that the inner claw has elasticity. The corrugated pipe with different diameters can directly insert into the clamping claw from outside, and the corrugated pipe cannot be dropped out directly.
