Abstract: The system comprises a clamping collar (10) suitable for being brought resiliently from its rest configuration in which its diameter is small to an expanded configuration. The system further comprises a support ring (20) suitable for being encircled by the collar, and an expander (40) suitable for co-operating with the ring firstly to hold the ring in an expanded configuration in which the collar (10) encircling the ring is also in its expanded configuration when the expander and the ring are in a first relative position, and secondly to enable the ring to contract and the clamping system to tighten under the resilient return force exerted by the collar encircling the ring when the expander and the ring are in a second relative position.

Abstract: Disclosed is a clamping device including a collar having at least one pair of projecting lugs and tightening means co-operating with said lugs. Each lug of a pair is equipped with reinforcement means suitable for opposing deformation of said lugs under the action of the tightening means. Each lug has a connection portion via which it is connected to a belt portion of the collar, which connection portion is upstanding relative to said belt portion, and a tightening wall, with which the tightening means come into engagement and which is folded back towards the belt portion. A space is formed between the connection portion and the tightening wall.

Abstract: The coupling (10) comprises a body (16) suitable for being fitted onto a tube (12) in leaktight manner, and a locking clip (22) that is elastically deformable between a locking configuration in which at least one locking zone (24A, 24B) of the clip can catch on a catch surface (14) of the tube and an unlocking configuration. The clip (22) is disposed over the wall of the body (16), which wall is provided with at least one transverse slot (30A, 30B) through which the locking zone (24A, 24B) projects into the body when the clip is in the locking configuration, and with at least one setback (32A, 32B; 36A, 36B) provided at the end of the slot, a portion of the bottom of said setback forming an unlocking ramp (34A, 34B; 38A, 38B) on which an unlocking zone (35A, 35B; 37A, 37B) can slide in order to cause the clip to go from its locking configuration to its unlocking configuration.

Abstract: A clamping system for connecting two tubes (20, 22) together in leaktight manner, the facing ends of the tubes having bearing surfaces (16, 18) that project relative to the cylindrical outside surfaces of said tubes. The system comprises a collar (10) and a washer (28). The collar has a band (12) suitable for co-operating with bearing surfaces via its inside periphery defining a setback, and a bolt (24) and a nut (26) arrangement for tightening the band (12). The washer is secured to the collar (10) by fixing tabs (32, 34, 36).
