An improved clamping collar of the type comprising a hooped band, one end of which mounts thereon a support for a rotatable screw which meshes with teeth stamped at the opposite end of the band. The support is formed by a portion having a U-shaped section which has longitudinal entrant portions which are fitted into the neck of the screw for providing the necessary support for same, and for preventing the screw from coming out on slackening of the clamping collar.
