ABSTRACT:
A connector is provided for a small diameter pipe that has been formed to include an annular swelled part near the end of the pipe. The connector includes a body with a communication hole extending axially therethrough. A chamber extends axially into one end and joins the communication hole. A window is formed through portions of the connector body defining the chamber, and a pawl extends across the window. The pawl includes a central portion that projects into the chamber. The pawl is configured to engage the annular swelled part of the pipe for holding the pipe in the connector body. The connector further includes a releasing member rotatably mounted around the connector body in proximity to the pawl. Outer circumferential portions of the releasing member define a cam wall configured such that rotation of the releasing member into a selected rotational orientation will deflect the pawl outwardly to enable release of the pipe.
