A coupling device for joining pipe ends has at least one pressing sleeve which can be slipped on a pipe end and pressed together with the pipe end. The pressing sleeve is elastically designed in the area of its inner surface pressed on the pipe end so that an expansion of the pipe end caused by temperature variations can be absorbed by elastic shear deformation of the elastic area, without causing the pipe end to slide in the pressing sleeve.
