<p>The device has a base body (14) fixed to a door structure or a guide rail, and a lever (16) articulated around an axis and mobile between door leaf passage and door leaf retaining positions. A helical spring (18) e.g. draw-spring and compression spring, maintains the lever in its retaining position. A braking device brakes the leaf when the leaf approaches its opening position and has an elastic element with projections forming frictional areas. A retaining roller (20) disposed on a retaining end (22) of the lever cooperates with a retaining unit when the lever is in the retaining position. An independent claim is also included for an assembly comprising a retaining device.</p> |
