Abstract
A coupling assembly includes a first coupling member that extends along an axis from a forward end toward a rearward end and includes a first locking surface and a first connection indicator positioned between the first locking surface and the rearward end. A second coupling member includes a receptacle for receiving the forward end of the first coupling member, an interior surface having a second locking surface and an exterior surface that may include a second connection indicator. A locking member is positionable between the first and second locking surfaces to connect the first and second coupling members. A release member is adapted to cover the first and second connection indicators when the locking member is positioned between then first and second locking surfaces and to expose at least one of the first and second connection indicators when the first and second coupling members are disconnected.
