Abstract
A brake hose coupling having a locking mechanism and a pressure relief valve for connecting a telemetry unit to the air brake pipe line of a railway train. The locking mechanism positively latches the brake hose coupling to the "glad hand" brake pipe hose coupling and causes the venting of the entrapped pneumatic pressure by the relief valve when the locking mechanism is unlatched.
