## Abstract

An interface arrangement (1) includes a plug connector (4) arranged on an interface board (3). Furthermore, the interface arrangement (1) includes an electrically conductive cover (10) at least partially surrounding the plug connector (4). The electrically conductive cover (10) is adapted to seal an interface opening of the housing, in which opening the plug connector (4) can be arranged, against electromagnetic radiation. The electrically conductive cover (10) includes at least one tab (19) with a latching device. The interface board (3) includes at least one receiving device, which is adapted to receive the at least one tab (19) and to latch with the latching device. A computer system with such an interface arrangement (1), and a method for assembling such an interface arrangement (1).
