Patent attributes
An open clamping ring (11) is provided for connecting tubes (1) that are provided with terminal flanges (2). The clamping ring is drawn together with the aid of a clamping lock that is provided at the open ends of the clamping ring. The clamping (10) substantially has the shape of a U whose legs that are composed of an inner leg section (12) and an outer leg section (14) are bent such that a clamping edge (13) is formed in the central area between the leg sections (12 and 14). The inventive clamping ring (10) thus approximately has the shape of an X. The clamping edges (13) rest more or less linearly on the outside of the final flange sections (2a) such that the friction between the clamping ring (10) and the terminal flanges (2) is reduced when the clamping ring is assembled while force is transmitted and distributed in an optimal manner.
