Abstract

A clamp connector for pipeline connecting pieces (5) has two clamping ring parts (1, 3) pivotably connected at one end between spread positions and clamping positions. A clamping device is situated at the opposite end of the clamping ring parts (1, 3) from the pivot connection (11). The clamping device has a clamping screw (19) pivotable from an active position with the clamping screw (19) interacting with the clamping ring parts (1, 3) to generate a clamping force pressing the clamping ring parts (1, 3) into the clamping positions, and a release position with the clamping screw (19) pivoted away from the clamping positions to release the clamping ring parts (1, 3). The clamping device has a locking device (25, 27) which, in its active state prevents the clamping screw (19) from being pivoted into the release position and which, as a function of the spread of the clamping ring parts (1, 3), passes through an opening angle from the active state into a release state in which the clamping screw (19) can be pivoted out.
