A door holdback device holds a door or panel in open position. It may be mounted upon the wall of a conventional boxlike highway trailer and is automatically retractable to an inoperative position. The holdback device has a primary wire loop extending from the wall, said primary loop being integrally attached to two secondary wire loops, which are then secured to the interior of the wall. The secondary wire loops are internally stressed to retract the primary loop when not in use. A second embodiment employs an internally stressed primary loop which moves about its supporting mount to assume an operative position.

In a holdback device for holding a door or panel in open position with respect to a wall of a highway vehicle or the like, the improvement comprising, in combination: a bracket for attachment to the wall, a flexible loop, means for attaching said flexible loop to said bracket to create an internal flexing stress in said loop, whereby in a first position said loop extends from said wall to engage an element on said door or panel, and in a second position said loop retracts into closer proximity with the wall solely caused by internal flexing stress existent within said loop.
