A butt connection of divided hollow profile members, which is suitable in particular for rotor blades of wind power installations, comprises a multiplicity of straps which are arranged along the joint and which bridge over same and which are respectively fixed with their ends to one of the profile members to be connected. In this respect the arrangement is preferably such that one of the two baits fixing the strap at the ends thereof has a wedge-shaped flattening, by means of which a tensile prestressing cap be imparted to the strap.
