1: Tool-holding device for a machining tool, comprising:
a tool-holder body; a receiving part defined in the tool-holder body; a retaining element provided with a pair of mutually cooperating jaws; a female seat between said jaws for an engaging male portion of a machining tip, said jaws being capable of taking a locking configuration, in which the engaging portion of the tip is firmly locked within the seat of the retaining element, and a disengaged configuration in which said engaging portion of the tip can be detached from the retaining element; a moveable component which bears the main load of holding the retaining element in said receiving part when the retaining element is in the configuration in which it engages the tip, wherein the tip and the female seat are configured so as to allow a snap insertion into the locking configuration of the tip within the female seat along a direction parallel to the bases of the retaining element, wherein the elastic element comprises a spring made as a single piece having a horse-shoe-like or “V”-like or “U”-like shape and housed in a seat provided in the jaws.
