Angular connection mechanism with instantaneous release for controlling winches and other apparatus driven by worm and hollow wheel, characterised in that the internal wall of the hollow wheel (5), mounted freely on the shaft (3b) connected to the rotating member (3-3a) of the winch or the like, includes at least one radial slot (5a) capable partially of receiving, under the effect of the movement of a plunger (11) with two diameters (11a and 11b) which can move inside a ball (3d) made axially in the aforementioned shaft (3b), at least one coupling ball (10) engaged in a radial opening (3c) formed in the wall of this shaft. Application to winches for safety apparatus of the type of smoke-clearing hatches and the like. <IMAGE>
