An expansion joint retainer is used in fastening a flexible elastomeric seal or strip seal to a structural slab. The retainer has a main body made from a first material. The main body has a thickness selected to permit emplacement of the retainer on the edge of a slab whereby the upper surface of the main body is substantially coplanar with or beneath the upper traffic bearing surface of the slab. The retainer includes a retaining element adjacent the lower surface of the main body. The retaining element is made of a second material serving to provide the retainer with sufficient rigidity to be bolted to a slab. The invention is characterized in that the second material is a thermoplastic elastomer.
