An air hose coupler for use in a tractor-trailer air brake system incorporates a body with a first air passage formed therethrough and a first mating face. The first mating face includes a first air orifice which communicates with the first air passage. A grip member is attached to the body and, in preferred embodiments, extends radially outwardly therefrom. The grip member includes a proximal end and a distal end, and a second air passage formed through the grip member from the proximal end to the distal end, with the second air passage pneumatically communicating with the first air passage. Additionally, the distal end incorporates a tapered neck and is adapted to communicate with an air hose such that the air hose pneumatically communicates with the second air passage. So configured, the grip member is graspable by an operator during engagement of the air hose coupler to a trailer coupler, thereby

[ I claim:] [15.] An air hose coupler for a tractor-trailer air brake system, the trailer having a trailer air hose and a trailer air hose coupler defining an air passage in communication with the trailer air hose, the tractor having a tractor air hose and a tractor air hose coupler defining an air passage in communication with the tractor air hose, the improvement therein comprising:said tractor coupler including a body having a mating surface for mating with a trailer air hose coupler, said mating face defining an air orifice communicating with said first air passage for alignment with the air passage of a trailer coupler;an elongated grip member having a proximal end rigidly mounted to said body and a distal end projecting from said body and extending approximately radially outwardly from said air orifice of said body;a first fitting extending outwardly from said distal end of said grip member for connection to a trailer air hose;a second air passage extending from said first fitting through said grip member to said first air passage of said body and pneumatically communicating with said first air passage of said body;said grip member being of stepped thickness of progressively decreasing breadths from said proximal end toward said distal end for grasping by an operator during engagement of said tractor air hose coupler;so that slipping of the hand of an operator from the distal end toward the proximal end of the grip is avoided during connecting of the tractor coupler to the trailer coupler.
