An oscillating quick-fit coupling for gardening machinery, includes a supporting structure designed to be fitted to a tractor, and a three-point linkage, connected to the machine, which is designed to be hooked onto the supporting structure, wherein the three-point linkage is connected to the machine via an articulated structure which allows the machine to perform limited oscillations in relation to the coupling. A series of hooks designed to engage corresponding elements integral with the coupling connected to the machine are fitted to the supporting structure connected to the tractor, which the hooks are equipped with devices designed to prevent the elements from becoming detached from the hooks, the devices being constituted by teeth which move between a position in which they interfere with the hooks and a retracted position, elastic structure designed to push the teeth into the interfering position being fitted.
