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 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. In preferred embodiments the locking members are spring biased toward a locking position where the locking member engages a flange to prevent the end plate from moving out of the fixed stretching position.

The tonneau cover apparatus according to claim 1, wherein each of the respective locking members are spring biased toward the first position and the elongated member is secured to each of the respective locking members such that force can be placed upon each respective locking member by pulling the elongated member in opposition to the respective spring biasing force biasing each of the respective locking members toward the respective first positions and drawing each of the respective locking members away from the respective first position toward the respective second position. 3. The tonneau cover apparatus according to claim 1, wherein the elongated member is a flexible member. 4. The tonneau cover apparatus according to claim 1, wherein each of the opposing side rails include an inwardly extending flange portion and each locking member includes a finger portion, the finger portion of each locking member being engaged with the inwardly extending flange portion of the respective opposing side rail when the respective locking member is in a first position, the finger portion of each of the respective locking members disengaging from the inwardly extending flange portion of the respective side rail when the respective locking member is moved from the first position to the second position. 5. The tonneau cover apparatus according to claim 1, wherein the end plate has an underside and each respective locking member is operatively connected to the underside of the end plate. 6. The tonneau cover apparatus according to claim 1, wherein each of the respective first and second locking members are biased toward the first position and force is required to displace each of the respective first and second locking members from the first position. 7. The tonneau cover apparatus according to claim 6, wherein each respective locking member is spring biased toward the first position. 8. The tonneau cover apparatus according to claim 6, wherein each respective locking member is spring biased toward the first position and each respective locking member is operatively connected to an underside of the end plate and positioned in such a manner that the support frame displaces each respective locking member from the first position to the second position for a brief period of time when the end plate pivots with respect to the support frame into the closed position. 9. The tonneau cover apparatus according to claim 6, wherein the end plate includes a pair of springs and each spring is operatively interconnected between the end plate and one of the respective locking members so as to provide a biasing force between the end plate and the respective locking member such that each of the respective locking members are biased toward the first position. 10. The tonneau cover apparatus according to claim 9, wherein the respective springs are selected from the group consisting of compression springs and tension springs. 11. The tonneau cover apparatus according to claim 10, wherein the spring is a tension spring. 12. The tonneau cover apparatus according to claim 10, wherein the spring is a compression spring. 13. The tonneau cover apparatus according to claim 1, wherein each respective side rail includes an inwardly extending flange portion and each respective locking member includes an outwardly extended finger portion, the finger portion of each respective locking member being engaged with each respective inwardly extending flange portion adjacent to the end plate and rearward of the respective first and second engagement positions with respect to the forward end when the tonneau cover apparatus is attached to the cargo box and each respective locking member is in the first position, the finger portion of each respective locking member disengaging from the respective inwardly extending flange portion when the respective locking member is moved from the first position to the second position. 14. The tonneau cover apparatus according to claim 13, wherein each respective locking member has an upper portion having a main body which is slidably retained by the end plate, each respective finger portion is spaced apart from each respective upper portion and extends outwardly beyond the main body of the upper portion, and each respective locking member is biased toward the respective first position and force is required to displace each respective locking member from the first position. 15. The tonneau cover apparatus according to claim 13, wherein each respective locking member includes an upper portion having a main body which is slidably retained by the end plate, and the finger portion is spaced apart from the upper portion and extends outwardly beyond the main body of the upper portion. 16.
