Abstract: A coupling part (1) for a fluid line coupling is provided with a locking element for locking in place a plug-in part that is to be introduced into the coupling (1), and with a checking element (8) to verify proper locking of the plug-in part. The checking element (8) is equipped with axially flexible spring arms (11, 12), which comprise an engagement structure (14, 15) devised to engage with a latching structure (15), and which, in a first checking position, block the checking element (8) from shifting into a second checking position if the plug-in part is not properly locked. After the second checking position has been assumed, as a result of the actuation by the plug-in part of an actuating structure formed on each spring arm (11, 12), the checking element (8) is out of engagement with the plug-in part, and it is therefore possible to remove the plug-in part from the coupling part in the second checking position of the checking part (8), as well, by actuating the locking element (5).

Abstract: An adapter integrates a tail piece and connection for coupling to plumbing fittings utilizing a union nut or flange and provides a press-fit connection to the tail piece for installation in the system.

The adapter can then be sealably attached to a plumbing fitting, such as a valve or the like, utilizing a conventional flat gasket between the flange of the adapter and the plumbing fitting. The installation is completed by inserting a conduit into the adapter to clear the O-ring and crimping the bead formed by the recess to complete the sealed connection.

Abstract: A latch and keeper combination is utilized for securing a radome to an aircraft fuselage. The keeper has a keeper housing and an eyebolt member which extends toward the latch from the keeper housing. The latch has a pivoting handle member pivotally attached to a latch housing. A hook member depends from the handle member. Once the hook member is generally placed about the eye bolt, depressing the handle member further causes the hook to rotate within the latch housing. As the handle member is completely depressed, the hook member fully engages the eye bolt, while at the same time members axially extend from the latch to engage the keeper which provides a resistance to shear between the latch and keeper. The apparatus may also have a safety which prevents the handle from fully closing until the eye bolt is fully engaged by the hook member, thereby providing visual confirmation that the latch has completely engaged the keeper.
