CLAMPING COLLAR WITH FOLDABLE RETAINING FINGER TABS

摘要

The clamping system for connecting a first tube and a second tube (2, 4) whose facing ends have projecting clamping surfaces (18, 20) comprises a collar (10) that comprises a belt (12) able to be clamped around said clamping surfaces and a washer supported by the collar. The belt (12) has a first and a second sidewall (13A, 13B) between which is delimited an internal recess able to receive the clamping surfaces. The washer carries at least one foldable retaining finger (22) which has a free end portion projecting axially beyond a first edge (13′A) of the belt over a distance sufficient to allow manual manipulation thereof, said free end portion having a retaining edge (21A) configured, when said end portion is folded towards the axis of the belt, to be retained outside the belt by a radially projecting element (2A).
