Abstract: A tonneau cover apparatus for attaching a flexible cover about a cargo box of a vehicle, preferably a pickup truck. The apparatus preferably includes, a support frame, including two side rails removably attached about the perimeter of a cargo box of the vehicle, an elongated flexible cover securing plate attached to an end of the flexible cover and a securing plate engagement member attached to the support frame, preferably one on each of the two side rails on each side of the support frame. The present invention simplifies securing and unsecuring of the securing plate to the support frame. The securing plate is preferably attached to an end of the flexible cover and is configured to cooperatively engage and pivot with respect to the securing plate engagement member and into and out of a closed or fixed stretching position wherein the flexible cover can be correspondingly be tensed and relaxed.

The apparatus preferably includes, a support frame removably attached about the perimeter of a cargo box of the vehicle, an elongated end plate attached to an end of the flexible cover, end plate engagement members attached to the support frame and first and second locking members movably connected with the end plate. The end plate may be retained in the fixed stretching position by first and second locking members that preferably slide within a channel in the end plate. In one embodiment, an elongated member is secured to the respective locking members and to a turn knob such that force can be placed upon each respective locking member by turning the turn knob and pulling the elongated member so as to draw each of the respective locking members away from the first position toward the second position.
