Hidden crochet, characterized essentially by being constituted by a tubular body of appropriate material and dimensions, open at one of its ends and provided on the opposite side of a rotary knob, a helical thread being included within said body to which a ring is threaded which is sliding, thanks to a guide stop, along an internal longitudinally open tube, whose ring has a clamp that retains pressure to the crochet itself, which is replaceable and capable of emerging and hidden by the tip or mouth open of the outer body, the central tube being joined to the aforementioned rotary knob to be moved by it in both directions for the purpose of advancing and retracting the working tip of the crochet hook.
