A modular retainer assembly is presented herein. The modular retainer assembly includes a first retainer module defining a flexible first retaining finger and a second retainer module that is distinct from and joined to the first retaining module. The second retainer module defines a flexible second retaining finger. When the first and second retainer modules are mated together, the first retaining finger is arranged opposite the second retaining finger. The first and second retaining fingers are configured to receive and retain an elongate article, such as a wire cable, between them.
