Abstract
Connection verifying device for a pipe and a connector has a body portion, a stop and verification arm and an abutment finger. The body portion includes an abutment plate and a fit-on portion. The stop and verification arm extends from an outer periphery of the abutment plate in one axial direction, while the abutment finger protrudes from one axial end of the fit-on portion in one axial direction. The abutment finger is arranged so as to abut and urge an annular projection of a pipe into an engagement slit of a retainer when the pipe and the connector are in half-fitting relation.
