1. An extensible cord lead comprising a casing containing a winding wheel (13) equipped, along its edge, with a series of notches (15) intercepted by a pushbutton (16) to allow partial or total blocking of a cord, whereby the pushbutton (16) is equipped with a forward position blocking device consisting of a cursor (20) which slides in a transverse direction with respect to a sliding axis of the pushbutton (16) in which it is inserted, said cursor (20) being activated by a thumb-turn (21) located on a head of the pushbutton (16), said cursor (20) being able to move from a blocked position to free sliding of the pushbutton (16), entering and exiting transversally to the sliding axis of the pushbutton (16), in a housing (22) in the casing of the winding wheel (13), wherein contact surfaces of the cursor (20) and of the thumb-turn (21) engage with each other. |
