Abstract
Abstract This latching device is used to couple connectable members together, one of which includes an adapter assembly having a valve plug, and the other of which includes a valve assembly having a valve plug receiving body. The adapter assembly includes an offset latch plug, and the valve assembly includes a latching unit engageable with the latch plug. The latching unit includes a slotted bracket member and an independent latch frame member capable of guided movement within the slots. A tension spring between these two members tends to pull them together. The latch plug includes a cammed nose portion and a transverse latch slot. The latch frame includes a cammed lip deflected by cam action and received into the latch slot to provide the latched condition. Unlatching is effectuated by depressing the latch frame.
