A retention device for securing expansion card shields ( 30 ) includes a chassis ( 10 ), and a lock member ( 20 ) for securing the expansion card shields to the chassis. The chassis includes a rear panel ( 12 ) with a flange ( 14 ) extending therefrom, and a holder bracket ( 123 ). At least a pivot slot ( 141 ) including an entrance portion ( 141 a) and a pivot portion ( 141 b) is defined in a junction area of the rear panel and the flange. The lock member has at least a pivot hook configured for being pivotally engaged in the pivot slot of the chassis. After the pivot hook of the lock member is inserted into the entrance portion of the pivot slot and slid to the pivot portion, the lock member can be rotated to a locked position for securing the expansion card shields on the holder bracket of the chassis.
