A coupling assembly is disclosed that includes a first member and a second member having a receiving portion sized to receive the first member. A retaining formation is provided on one of the first and second members. The retaining formation includes a ramp and two or more grooves, wherein each groove is at least partially defined by converging surfaces. A locking member is moveably secured in a cavity in the other of the first and second members. The locking member is configured to be moved in a first radial direction by the ramp upon movement of the first member into the second member. The locking member is also biased in a second radial direction opposite the first radial direction into a groove in the retaining formation to become positioned between a converging surface on the retaining formation and the cavity upon further movement of the first member into the receiving portion of the second member, and may be progressively received in additional grooves on the retaining formation if the first member is further inserted into the second member.

Coupling assembly

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.

Coupling assembly with connection indicator

The present invention includes a pre-assembled, high-pressure coupling interface adapter for use with a non-threaded port of a female member. The adapter comprises a generally cylindrically shaped metal body including a central longitudinal channel and an inner and outer surface. The body includes an external segment having an external end and an internal segment having an internal end, the internal segment configured for receipt within the port of the female member. The inner surface of the body is configured to engage and secure one or more external features of a separate male coupling member. The present invention also includes a coupling assembly including a coupling adapter and a method for forming a female coupling assembly including an adapter.
