| 摘要 |
The invention relates to a connector for tubing, consisting of a body and a screw insert, the material forming the insert being a plastic material with high mechanical resistance and the material forming the body being a thermoplastic resin. The insert is partially or completely housed in the body of the connector, tightly coupled thereto by means of an anchoring system consisting of at least one circular or polygonal ridge formed on the outer face of the insert, the ridge(s) peripherally surrounding the cylindrical wall of the insert. The separation between the ridges creates at least one groove into which the thermoplastic material forming the body of the connector penetrates, enabling the long-term tightness of the connection. The structure of the connection can include a reinforcement ring which provides the connector with a resistance higher than that provided solely by the insert material.
