Abstract:
1. A connector clip for verifying complete connection between a connector and a pipe to be put thereon and mounted thereto; the connector having a tube connection portion on one axial side thereof and being provided with sealing member in an inner peripheral surface thereof; the pipe being provided with an annular engagement projection and an annular verification projection on an outer peripheral surface thereof, and being relatively inserted into an opening on an axial end of the connector so as to allow an inserting end thereof to be located beyond the sealing member and the annular engagement projection to be snap-engaged with the connector; and the annular verification projection being formed so as to be located in or near an opposite axial end of the connector, or on an opposite axial side of an opposite axial end of the connector; comprising: a clip body including a connector receiving recess of U-shape in cross-section and formed with a radially inwardly directed extending portion on one axial end thereof, the connector receiving recess having an opening and being formed to receive a large diameter portion on an opposite axial side of the connector therein, a connection verifying portion provided on an opposite axial end of the clip body and separated therefrom, and including a pipe receiving recess of U-shape in cross-section with width equal to or generally equal to an outer diameter of a body of the pipe, the pipe receiving recess having an opening and being formed to receive an opposite axial end of the pipe therein with respect to the annular verification projection, a circumferentially extending reinforcement rib formed integrally on a radially outer peripheral surface of the connection verifying portion to increase widening resistance of the pipe receiving recess, the radially inwardly directed extending portion and the connection verifying portion being arranged so as to hold a portion from one axial end of the large diameter portion to the annular verification projection of the pipe from axially opposite ends thereof, and the clip body and the connection verifying portion being integrally connected with one another via a connection part at an opposite position of the openings of the connector receiving recess and pipe receiving recess.
