LOCKING DEVICE FOR AN AIR BRAKE HOSE COUPLING MEMBER

摘要

A locking device (50) for a pair of mating air brake hose coupling members (20) includes a housing (52) with a first aperture (56) for attachment to one air brake hose coupling member (20) and a second aperture (58) for attachment to a hose support member (14) which is adjusted to provide a predetermined clearance between the air brake hose coupling (20) and a rail track (18). A locking pin (60) is reciprocally disposed within the housing (52) and is being urged by a resilient member (62) in one direction for preventing undesirable complete rotational uncoupling of such pair of mating air brake hose coupling members (20). The locking pin (60) is manually movable in the opposite direction during coupling and uncoupling under normal operating conditions.
