The clamping collar comprises a flexible strap (2) having transverse notches (14) and a fastening head (1) with a passage (8) for insertion of the strap. The passage is delimited by a crosspiece (6) carrying a non-return catch (11) comprising teeth (13) which engage the notches. A tab (16) projecting from the crosspiece opposite the passage is located facing the catch and the bringing together of the tab and the catch cause the catch to pass into an unscrewing position. |
