<p>A description is given of a slider (1) with two pull tabs (2, 3) arranged symmetrically with respect to each other and each provided with a ring (2a, 3a), the slider comprising a hollow body (4) containing an escapement (5), the pawl (6) of which is designed to be inserted between the teeth of the zip in order to prevent movements between the zip and the slider (1), the escapement (5) being provided with elastic means (7) which keep its pawl (6) inserted between the teeth until it is disengaged by one or other of the pull tabs (2, 3). In the slider in question one (2) of the pull tabs (2, 3) is in contact with the escapement (5) via its ring (2a) in such a way that, when operated, it produces the said disengagement, and the other pull tab (3) is positioned with its ring (3a) in contact with an inclined plane (8) of a rigid member (9) which is positioned in such a way that operating the abovementioned pull tab (3) causes a rotation of the rigid member (9) sufficient to press it against one end (20i) of a movable pin (10) and to move it axially in such a way that the other end (20s) pushes the escapement (5), overcoming the resistance of the said elastic means (7) and disengaging the pawl (6) thereof. <IMAGE></p> |
