摘要
Provided is a pipe connector having high resistance to pullout force and having high durability. The outer diameter of a nipple (20) is substantially uniform when viewed in the lengthwise direction. The end part of a hose (24) is placed over the nipple (20). A spring (32) is wound around the outer circumference of the hose (24) such that no gap occurs between adjacent wires. The shaft part of a connector main body (14) supports the nipple (20). A fastening nut (26) has an internally threaded part (28) which meshes with an externally threaded part (16) provided on the connector main body (14), and encloses the end part of the hose (24) together with the connector main body (14). The spring (32) is compressed by tightening the threaded part of the fastening nut (26). The end part of the tightly wound spring (32) rotates and the outer diameter thereof is reduced, thereby generating high fastening force. Thereafter the fastened state is maintained by frictional force.
