Abstract
Abstract A fastening device permitting parts to be mounted to a protuberance on a support surface. The device includes a body with a recess adapted to receive the protuberance and including adhesively coated surfaces within the recess for adhering to the protuberance. A fastening member having an axis generally parallel to the adhesive surfaces is preassembled to the body in such a manner as to insure that the adhesive is loaded primarily in shear.
