Abstract: The clamping system comprises a collar (10) having a band (12) that has two flanks (13A, 13B), between which an inside trough (14) is defined that receives projecting clamping surfaces (1A, 2A) of two tubes (1, 2) to be assembled together. The system further comprises a plurality of individual retaining clips (20) distributed angularly around the first flank (13A), each clip having an inside branch (30) and an outside branch (32) facing each other, and between which the first flank is pinched, and a retaining portion (34) that, in the pre-attached state, is suitable for co-operating with the clamping surface (1A) of the first tube (1), one of the branches carrying a first bearing zone (36) that co-operates with a first bearing surface (13?A) of the collar that faces towards the axis (A) of said collar.

Abstract: A clamping collar having a hook (22) suitable for being clipped onto a lug (12) in the clamped state. The collar has a tongue (14) secured to the end that carries the hook (22). The lug (12) has a free edge (12A) which, when the collar is in the unclamped state, faces towards the hook (22), and the tongue carries at least one retaining member (26A, 26B) which, when the collar is in the unclamped state, lies in a cavity (28) provided under the lug (12) and co-operates with the free edge thereof. The tongue also has a guide embossed region (40) in alignment with the free edge of the lug to guide said lug during hooking and/or to form an abutment for the hook.
