The rail vehicle integrity check device 20 comprises a first connector 21 adapted to form an airtight connection with the brake pipe 22 mounted on the rear wagon of a rail vehicle, and a second connector 23 adapted to form an airtight connection with a main reserve pipe 24 mounted on the rear wagon of the rail vehicle. A one-way valve 25, adapted to be in fluid communication with the brake pipe and the main reserve pipe of the rear wagon of the rail vehicle, is mounted between the first 21 and second 23 connectors. This may be done by providing elbow joints 26, 27 between each of the connectors 21, 23 respectively and the one-way valve 24. For convenience, the one-way valve 24 and any elbow joints 26, 27 provided may be housed within an external casing 28 in order to prevent the ingress of dirt whilst in use. The pipe connectors 21, 23 may be connectors used widely within the railway industry, such as angle cocks or gladhand couplers, or screw thread connectors, push and turn locking mechanisms or push fit connectors. Suitable flexible closure element one-way valves 25 include, but are not limited to, diaphragm check valves, duckbill valves or reed valves. Suitable hinged closure element one-way valves include, but are not limited to, swing check valves, butterfly check valves or tilting flap check valves. The one-way valve 25 comprises a chamber 29 and a pressure-sensitive closure element 30 abutting a closure surface 31 within the chamber 29.
