Abstract: The invention relates to connecting device (27) comprising a screw (1) and a carrier (7, 70), the latter being provided with a hollow space (8, 9, 28, 29) for receiving therein said screw (1), said hollow space (8, 9, 28, 29) being in frictional and/or positive engagement with the thread (3) of the screw (1) upon insertion of said screw (1). The hollow space (8, 9, 28, 29) is provided with a membrane (11) which can be penetrated by the screw (1) and which is arranged substantially transversely to the longitudinal screw axis (Y), said membrane (11) forming a skirt (15), which encloses primarily the thread (3) at least partially, while undergoing deformation during insertion of the screw (1). The invention further relates to a method for creating a screw connection by inserting a screw (1) into a carrier (7, 70).
