Disclosed is a locking device for securing an unattached trailer. The device includes an elongate, flat and ductile bar, along which two 90°transverse bends are made, forming a medial base and parallel and opposed first and second arms. A locking pin is mounted to the base and extends in the direction of the arms, and first and second retainer openings are formed near the free end of the first and second arm, respectively, and beyond the locking pin. The device is secured to a brake line coupler by insertion of the locking pin into the air passage recess of the coupler so that the arms extend beyond the coupler, then by securing either padlock shackle or a retaining bolt through the first and second openings.

A security device for releasable connection to a brake line coupler of a trailer, said device including: a generally planar, substantially rigid base and means forming an aperture through said base; an elongate locking pin extended through said aperture and away from the base in a direction generally perpendicular to the plane of said base, and a fastening means on one side of said base for integrally securing the pin with respect to the base; a first locking arm extended from one end of the base and inclined with respect to said plane; and a second locking arm extended from the opposite end of the base and inclined with respect to said plane; a substantially rigid retaining member; a first retaining means formed near the free end of said first arm; and a second retaining means formed near the free end of said second arm; said retaining means adapted for mutually releasably engaging said retaining member and, when so engaging said retaining member with said locking pin inserted into a recess open to one side of a trailer brake line coupler, cooperating to secure said retaining member on the opposite side of said brake line coupler to prevent removal of said pin from said recess.
