An improved gladhand security lock apparatus is locked to a gladhand brake line coupler to immobilize a trailer.

A guard plate is formed on an end of the body and a clip with an upturned rail member is formed parallel to the guard plate and spaced therefrom. The security lock apparatus is attached to the gladhand coupler so that a tongue of the gladhand is received in the tongue receiving bight, the abutment surface of the security lock apparatus overlies a port of the gladhand coupler, and a retainer flange formed on the gladhand coupler is received between the guard plate and the clip. The security lock apparatus body comprises a barrel. A lock housing is formed in a bore in the barrel perpendicular to and confronting a keeper bolt positioned in a keeper bolt receiving bore. A lock cylinder in the lock housing is operative to drive the keeper bolt across the tongue receiving bight from an opening in the abutment surface to engage the retainer. In operation,…
