摘要

The system is assembled of a screw (15) guided through a threaded sleeve (18) and protruding from the lower end of the sleeve (18) after insertion in order to be joined to a counter bearing (26). The sleeve (18) can be accommodated in a groove (13) at a first profile (11), the counter bearing (26) in the groove (14) at a profile to be joined. A locking element designed in a cross shape and made of a flexible material is folded around the tip of the screw (15), holding screw (15) and sleeve (18) connected during transport and insertion and can be removed as soon as the tip of the screw (15) protrudes from the lower end of the sleeve (18).
