A through flow coupler comprises two parts having intercommunicating passages therein so that fluid can flow through the two parts. A sealing member provides a fluid tight seal between the two parts when the two parts are held together in a sealed condition. A pressure sensitive device, which may comprise a frangible ring, holds the two parts in the sealed condition when the fluid pressure within the passages is below a certain value and allows the two parts to move relative to one another to a pressure relief condition so that fluid can escape from the passages when the fluid pressure within the passages exceeds said certain value. Also, mutually co-operable members, e.g. flanges, are provided to prevent total separation of the two parts when the pressure sensitive device allows the two parts to move relative to one another.

A through flow coupler comprising first and second parts having intercommunicating passage means so that fluid can flow through the first and second parts, sealing means for providing a fluid tight seal between the first and second parts when the first and second parts are held in a sealed condition relative to one another, pressure sensitive means for holding the first and second parts in the sealed condition when in use the fluid pressure within said passage means is below a certain value and for allowing the first and second parts to move relative to one another to a pressure relief condition in which fluid can escape from the passage means when in use the fluid pressure within said passage means exceeds said certain value, and means preventing total separation of the first and second parts when the pressure sensitive means allows the two parts to move relative to one another.
