An interface card coupling structure includes a bracing member fastened to a case that has a retaining plate extending from an edge with a latch hole formed thereon, and a coupling member pivotally coupled on the retaining plate. The coupling member has a latch pin on one end facing the retaining plate to engage with the latch hole and anchor the coupling member on the retaining plate. The coupling member presses an interface card to form secure coupling. The coupling member may be made by injection forming. The structural elements of the bracing member of the interface card coupling structure are thus fewer. Hence the cost may be reduced and production speed increased.

A retaining device for a heat sink includes a retaining piece, a retaining arm, a connection seat and a control member. The retaining piece has one end formed with a retaining hole and a top end formed with two tabs. The retaining arm has a vertical surface formed with a retaining hole. The tabs penetrate through the retaining arm and then the connection seat having an accommodating slot. The control member has a disk and a handle connected thereto. The disk in the accommodating slot has a hollow eccentric control slot. A pivot mounted to the tabs may slide in the control slot. The control member is rotated to move the pivot, which causes a relative movement between the retaining piece and the connection seat so that the retaining hole retains a mounting seat of the heat sink while the retaining arm tightly presses against the heat sink.
