Hinge for closing panels of the access opening of refrigerated cabinets, where said hinge comprises: - a casing that can be fixed to a fixed frame of the access opening, where said casing contains a mechanism configured to allow the rotation of said panel about an axis between a closed position and an open position of the access opening of the refrigerated cabinet, - an elastic return means to allow the return from the open position to the closed position of the panel; and - a braking element configured to interact with the aforesaid mechanism to brake the closing movement of the panel generated by said elastic return means, the mechanism configured to allow the rotation of said panel about the axis comprises a crank adapted to be placed in rotation by the opening and closing movement of said panel, said crank being kinematically connected to a connecting rod in turn connected to a piston, wherein the braking element comprises a lever configured to interact in oscillation with the mechanism that allows the rotation of said panel about the axis, where said oscillation movement takes place from a first position in which the lever does not interfere with the movement of the aforesaid mechanism to a second position wherein said lever interacts with the aforesaid mechanism to brake the closing movement of the panel to which the hinge is connected, wherein the oscillation movement of said lever about a fulcrum thereof is opposed by the resistance of a spring acting on the aforesaid lever, wherein the braking element further comprises a skid provided with a surface configured to be engaged with a corresponding surface pertaining to said lever, wherein the piston has a raised element, where said raised element is adapted to interact with a corresponding raised element pertaining to the skid so that said skid acts on the lever pressing it against the spring, where said spring acts on the lever bringing it into the second position so as to slow down the stroke of the piston. - a casing that can be fixed to a fixed frame of the access opening, where said casing contains a mechanism configured to allow the rotation of said panel about an axis between a closed position and an open position of the access opening of the refrigerated cabinet, - an elastic return means to allow the return from the open position to the closed position of the panel;
