<p>The arrangement (2) has a body (3) mounted on a support i.e. lid. The lid is mounted on a structure i.e. machine. A fixation screw (4) fixes the body on the support, where the screw is mobile between a position in which the screw fixes the body in a mounted position on the support and another position, where the body is dismounted in the latter position. The screw is connected to the body by a connection unit i.e. spiral (5), where the connection unit allows disassembling of the body from the support and rotation of the screw.</p> |
