ABSTRACT:
A connector includes a first member and a second member. The first member includes a conduit having a ring-shaped projection formed at a rear end and a tubular body having first engagers and second engagers. The second member has a tubular shape, and includes third engagers and a presser formed adjacent to a rear end. The ring-shaped projection of the conduit engages with the first engagers of the tubular body, thereby preventing a relative movement between the conduit and the tubular body in an axial direction in the first member. Further, the second engagers of the tubular body engage with the third engagers of the second member, thereby preventing a relative movement between the first member and the second member in an axial direction in the connector. The presser of the second member presses the tubular body of the first member inwardly in a radial direction, thereby preventing a relative movement between the first member and the second member in a direction being perpendicular to an axial direction in the connector. Thus, the connector exhibits remarkably strong forces for engaging the first member with the second member in an axial direction as well as in a direction being perpendicular to an axial direction.
