A hopper latch for a refuse compactor truck provided with hydraulic cylinders for opening and closing the hopper, the hopper latch comprising:

• two hook-shaped plates, one for the left side and the other for the right side of the truck, configured to hold the hopper and avoid the lifting of the hopper during refuse compaction;
• two manifold studs, one for the left and one for the right side of the truck, configured to connect elements of a lower part of the hopper latch and expand a stroke adjustment of the hook-shaped plates, each manifold stud fixed to a container of the truck by passing one end of the respective stud into a hole at a lower part of the truck and another end of the stud is welded to a respective one of the hook-shaped plates;
• two springs placed on sides of the manifold stud, one for an upper and one for a lower side with respect to the manifold stud, located between the respective hook-shaped plate and the container of the truck, to cushion a load between the hook-shaped plates and the container of the truck and facilitate the hook-shaped plates' adjustment;
• fastening elements, including a set of the fastening elements for the left side and a set for the right side of the truck, arranged to maintain the manifold studs fixed and therefore the hook-shaped plates to the refuse compactor of the container of the truck and to serve as adjustment elements of the hook-shaped plates;
• and two upper supports with an elliptical cavity, configured to work as a variable rotation point and to guide the hopper's lifting and lowering movements, such that the hopper is automatically coupled with the hook-shaped plates.
