Abstract
Fretting wear in a pipe connector is avoided in advance.In a connector body (1), there is provided a gate member (29) having spring portions (33) that allow a pipe (P) to be inserted up to a regular depth while maintaining a contact state with the pipe (P). When a retainer (37) is pushed in with the pipe (P) being inserted to the connector body (1) up to the regular depth, locking legs (45) of the retainer (37) are locked to a bulge portion (6) of the pipe (P) and each locking leg (45) enters between the pipe (P) and the spring portion (33) and elastically displaces the spring portion (33) in a direction away from the pipe (P), thereby eliminating the contact state.
