Patent attributes
A pipe connector includes a connector body, a retainer having a pair of locking legs and a release operation portion, and a checker. The connector body has an insertion hole into which a pipe is insertable. The locking legs are deformable to be spread and closed and are moved into the insertion hole. The release operation portion being operable to displace the locking legs in a direction such that the pipe is releasable from a retained state. The checker is formed separately from the retainer and lockable to the connector body and releasable from a locked state to be movable to a detection position when the pipe is inserted into the insertion hole. The checker is formed with pressing pieces located rearward relative to the locking legs when the checker assumes the detection position, to thereby prevent the locking legs from being flexed rearward.
