The connector element is having a threaded element complementary to the threads of the threaded end configuration of the second tubular element, a tube lock that is co-axially arranged with respect to and disposed downstream of the threaded element for holding the second tubular element, and a guide element that is co-axially arranged with respect to and disposed down-stream of the tube lock for guiding the second tubular element.

Abstract: According to one aspect, a quick disconnect connector is provided. The quick disconnect connector includes a first component and a second component which is matable with the first component. A releasing element is engageable with at least one of the first component and the second component to unmate the first component and the second component. A locking element is movable between a locked position and an unlocked position. The locking element, in the locked position, engages the releasing element to prevent the releasing element from unmating the first component and the second component. The locking element is movable from the unlocked position to the locked position by application of a locking force to the locking element. The locking force can be applied to the locking element by fluid being carried by the quick-disconnect connector.

Abstract: A retainer is equipped with a regulation segment, which regulates the position of an O-ring placed in an insertion hole, and a prevention segment, which engages with a spool of a pipe and prevents the pipe from being removed from the insertion hole. Moreover, by moving the retainer toward the minus side in the Y direction and attaching it to an attachment segment, the retainer becomes sandwiched between an opposing wall portion and a tube segment in the X direction. Because of this, the number of parts can be reduced and the retainer that regulates the position of the O-ring can be prevented from being moved in the X direction by the pressure of fluid flowing inside the pipe connector in the X direction.
