A clamping ring closure with a locking unit has a clamping lever (1), linkage arm (3) and an attachment plate (6). The locking system comprises a barb-like fastening which is effected between the hook-like element (16) and a lock bolt (2) on the other locking element. Initial opening of the clamping ring is only possible by the application of force and uniform deformation of the interlocked hook and bolt. In one design the hook element (14) engages in a tongue (16) on the one attachment plate (8) and is guided on a corrugate surface on the plate (8). |
