ABSTRACT:
A water pipe connector includes a pipe coupling portion surrounding an axis and adapted to be sleeved on one end of a water pipe, a clamping component having resilient arms that extend between the pipe coupling portion and the water pipe and that have engaging members projecting through radial holes in the pipe coupling portion, and a locking collar. The locking collar is sleeved on the pipe coupling portion, has an internal collar surface formed with a plurality of first grooves, and is rotatable about the axis between an unlocking position, where the engaging members are received respectively in the first grooves, and a locking position, where the internal collar surface abuts against the engaging members and urges the resilient arms to abut tightly against the water pipe so as to arrest removal of the water pipe from the pipe coupling portion.
