The invention relates to a device for joining precast concrete parts, consisting of at least one cable loop. One end of said loop is anchored in the precast concrete part and the other end, which is provided in the form of a loop, co-operates with a holding device which is arranged in or on the precast concrete part. This enables the cable loop to be elastically bent in a perpendicular manner during the production process and to be released for joining purposes. According to the invention, at least one fixing element holds the joining cable loop.
