摘要：
An improved hose coupling for railway vehicle brake pipe hoses, which hose coupling is characterized by a nipple portion disposed at an angle relative to the axis of the coupling head and an angular extension of the lower end of the coupling lip for preventing premature or inadvertent uncoupling due to excessive bouncing motion of the vehicle and, therefore, vertical oscillation of the hoses.
