The present disclosure relates to a holding assembly to hold a front frame of a thrust reverser to a turbojet engine casing. The assembly includes at least one connecting flange connecting the front frame to the turbojet engine casing, and also a system for locking the connecting flange. The system includes an actuating handle pivotally mounted on one of two facing ends of the connecting flange, and a connecting rod interposed between the other end of the two facing ends and a portion of the actuating handle. The system locks together the two facing ends, and the actuating handle includes a support provided with a groove and a screw for adjusting a free length of the groove. Furthermore, the connecting rod has, at its one end, an axis pivoting and sliding in the groove.

1. A holding assembly for holding a front frame of a thrust reverser to a turbojet engine casing, comprising: at least one connecting flange connecting the front frame to the turbojet engine casing; anda system for locking said at least one connecting flange, the system locking together two facing ends of said at least one connecting flange, the system comprising: an actuating handle pivotally mounted on one of the two facing ends of said at least one connecting flange; anda connecting rod interposed between the other end of the two facing ends and a portion of the actuating handle separate from an axis of rotation of the actuating handle,wherein the actuating handle comprises a support having a groove and a screw for adjusting a free length of the groove, and the connecting rod comprising, at one end thereof, a pin adapted to pivot and slide in the groove so that the pin abuts an end of the groove, in an open position or a closed position of said at least one connecting flange, and the pin of the connecting rod abuts a screw situated another end of the groove, respectively, in the closed position or the open position of said at least one connecting flange. 2. The holding assembly according to claim 1, wherein the actuating handle further comprises an arm slidably mounted on the support and comprising a blocking element so that, in the open position of said at least one connecting flange, the arm is in a retracted position on the support, whereby the blocking element of the arm blocks the pin at one of the ends of the groove. 3. The holding assembly according to claim 2, wherein the blocking element comprises a blocking finger formed at an end of the arm. 4. The holding assembly according to claim 2, wherein the blocking element comprises an adjustable wedge formed at an end of the arm. 5. The holding assembly according to claim 2, wherein the actuating handle is pivotally mounted on one of the two facing ends of said at least one connecting flange between a locked open position and a locked closed position. 6. The holding assembly according to claim 5, wherein the arm of the actuating handle comprises a blocking bolt capable of cooperating with at least two strikers secured to one of the two facing ends of said at least one connecting flange, and the blocking bolt configured to lock the actuating handle in the corresponding closed and open positions. 7. The holding assembly according to claim 6, wherein said at least two strikers are distributed over an outer surface of a bracket secured to one of said at least one connecting flange. 8. The holding assembly according to claim 6, wherein the blocking bolt cooperates with the two strikers secured to one of the two facing ends of said at least one connecting flange in a retracted position of the actuating handle. 9. The holding assembly according to claim 1, wherein the support of the actuating handle is pivotally mounted around a longitudinal axis of a bracket mounted at a free end of the at least one connecting flange. 10. The holding assembly according to claim 1, wherein the connecting rod is mounted on the another end of the two facing ends of said at least one connecting flange by a ball-joint or pivot connection. 11. The holding assembly according to claim 1, wherein the screw is adapted for defining a dead stroke of the actuating handle. 12. The holding assembly according to claim 11, wherein the screw is slidably mounted on the support, while cooperating with a nut mounted on the support of the actuating handle. 13. The holding assembly according to claim 1, wherein the connecting rod is of a different length to adjust a clearance between the the two facing ends of the connecting flange. 14. A propulsion assembly comprising a turbojet engine housed in a nacelle capable of being connected to an aircraft by an attachment mast, the turbojet engine comprising fan blades surrounded by a casing mounted edge-to-edge with a front frame of a downstream structure of the nacelle, said propulsion assembly including the holding assembly according to claim 1. 15. The propulsion assembly according to claim 14, wherein a length of the actuating handle goes beyond a volume of the nacelle when the actuating handle is in the open position.
