ABSTRACT:
An improved element for the connection of lift straps (28) of rolling shutters, placed in a container (12) provided with a lid (14), is constituted by a semirigid sheet with a quadrangular back portion (18) and a "T"-shaped front extension (20). The back portion (18) meets the wall (22) of a tongue (24) which extends towards the inside of container (12), while the "T"-shaped extension (20) protrudes from the container through an opening (26), approaching its perimeter surface. The "T"-extension (20) is hand-inserted into a slot (30) provided at the end (28') of the lift strap (28); the vertical branch (20') of the "T"-extension (20) is positioned under the end (28') and fits through the width of opening (26).
