ABSTRACT:
A safety attachment for a two component air line "glad hand" coupling employed on tractor trailers and railway rolling stock is disclosed. The attachment is secured to one part of the coupling and includes a rigid blocking member which prevents relative rotation of the two coupling parts in a direction which could allow separation of the two coupling parts.
