A technique is described whereby circuit cards which are plugged into microprocessor systems are retained in card holders through the use of a card guide locking arrangement, so as to prevent the circuit cards from becoming unseated or from becoming dislodged due to vibration. The card guide, as shown in Fig. 1, is fabricated with two sets of serrated teeth 10. The card guide lock 15, as shown in Fig. 2, also has two sets of serrated teeth of the same pitch and size as those in the card guide. After a circuit card is installed using the card guide, card guide lock 15 is inserted between the end section 11 of the card guide. The serrated teeth of both parts will mesh together to form a restrictive force against the circuit card. This restriction will prevent the circuit card from becoming dislodged.
