An anti-theft device for securing an article of merchandise against unauthorized removal from a display counter. The anti-theft device includes two mating bracket members. Each bracket member includes a lip configured to engage a lateral side of the article of merchandise. The bracket members are configured to be independently placed onto the opposite lateral sides of the article of merchandise and then coupled together. The collective length of the bracket members is less than the distance between the lateral sides of the article of merchandise, thus creating a gap between the bracket members when the article of merchandise is initially received therein. A fastener connecting the bracket members together is operated to reduce the width of the gap, thereby causing the bracket members to exert compressive forces onto the lateral sides of the article of merchandise.
