Various implementations include methods and apparatuses for connecting concrete structural elements, such as pre-cast concrete structural elements. In one implementation, an apparatus includes a first concrete structural element into which a first duct is pre-cast, a second concrete structural element into which a second duct is pre-cast, and a duct coupler that couples the first duct in fluid communication with the second duct and prevents adhesive from flowing into the first or second duct when the first and second concrete structural elements are coupled together. In another implementation, a method of forming a concrete structural element includes disposing at least a portion of a duct within a form for receiving poured concrete, disposing a duct holder through an opening in the form and coupling the duct holder with the duct to hold the duct in position within the form during pouring, and removing the duct holder after the concrete hardens.
