Abstract
A sound decoupling connecting element (1) for two parts (27, 28) with a gasket (29) inserted inbetween has a screw (2) with a head (4) and a shaft (8) with a threaded section (10, 11) and a radially extending support area (14) resting on a counter surface in the end-mounted position. The connecting element (1) has a sound decoupling sleeve-like formed body 3 made of an elastomer material. The formed body (3) has limited axial movement on the screw (2) in the mounted state of the connecting element (1), but is held in an unlosable fashion. The formed body (3) has such an axial length that it protrudes the first part (27) with a continuation (19) in the direction of the gasket (29) in the state of being inserted in the first part (27). The continuation (19) of the formed body (3) has a recess (20) for taking up in an unlosable fashion the gasket (29). At least one friction area pairing (22), which holds and aligns the screw (2) in every position over the lift (26) of the limited axial movement, is provided between the formed body (3) and the screw (2).
