Coupling structure used for coupling fluid pipes in engine compartment of motor vehicle, has screw that is penetrated into threaded hole formed at inclined surface, for increasing locking force of locking projection portions

摘要

The coupling structure (1) has coupling elements (10,12) that are provided at one side of a limited flow channel (5), and an engaging mechanism (21) for hooking the coupling elements. A latching mechanism (22) is arranged at the opposite side of flow channel, for locking the coupling elements. The front and rear locking projection portions (35,36) are arranged for receiving the coupling elements in a recess (31). A screw (29) is penetrated into a threaded hole (28) formed at an inclined surface (38), for increasing the locking force of locking projection portions. An independent claim is included for method for joining coupling elements of coupling structure.
