Patent ID: 7316428

Claim:
An assembly for verifying complete mechanical connection between a pipe and a connector, said assembly comprising: a generally cylindrical connector and a pipe inserted therein, the connector including a tube connecting portion on one end thereof and retainer means on the other end thereof, the retainer means having a connection engageable portion on a non-engageable part at a position displaced circumferentially from the connection engageable portion; the pipe having an inserting end portion formed with an annular engagement projection on an outer peripheral surface thereof, the inserting end portion being inserted in the connector via an opening so that the annular engagement projection is snap-engaged with the connection engageable portion; a connection verifying device for the pipe and the connector mounted to the pipe and the connector to verify mechanical connection between the pipe and the connector, the device, including: a body portion mounted to the other end of the connector; an abutment finger protruding from the body portion in one axial direction, and entering in the connector via the opening, and further formed so that one end of the abutment finger extends to an axial position of the connection engageable portion on the non-engageable part of the retainer means; verification means constructed on the body portion and having an engaging portion, the engaging portion being engaged in the other axial direction with a stop portion formed on an axially fixed portion of the connector; said engaging portion being formed to be positioned spaced in the other axial direction from the stop portion of the connector when the abutment finger abuts the annular engagement projection of the pipe which has not yet engaged with the connection engageable portion; and said abutment finger being formed further so as to move the annular engagement projection in one axial direction with respect to the retainer means to engage the annular engagement projection with the connection engageable portion when the abutment finger moves the annular engagement projection of the pipe from the position in which said annular engagement projection has not yet engaged with the connection engageable portion of the retainer means; and the stop portion being in a form of an engagement window provided in the connector for being engaged with the retainer means and thereby restraining the retainer means from escape from the connector.
