摘要

A system for attaching a structural member to a supporting member, the supporting member having at least one stud which extends through an opening of the structural member, the system comprising the following features: a sleeve having a radial flange at one end adapted to be introduced into the opening an annular sealing element positioned on the sleeve and adapted to engage the associated surface of the structural member an integral nut arrangement, preferably of spring steel which has a nut portion adapted to be threaded onto the stud a fastening portion adapted to be secured to the flange, the fastening portion being rotatable with the flange and engages axially the radial flange of sleeve and a deformable portion between nut portion and fastening portion which allows a certain axial deformation if the nut arrangement is threaded onto the stud with a predetermined torque into engagement with the radial flange, the deformable portion and the fastening portion forming a passage for the stud.
