摘要： A clamping system for connecting a first and a second tube whose opposite ends have clamping surfaces protruding from the cylindrical outer surface of the tubes. The system includes a collar having a belt able to be clamped around the clamping surfaces. The belt includes a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries an external retaining device having a retaining bar, which protrudes axially from the first flank while being oriented transversely to the axis of the collar and which has a transverse retaining ridge, the bar being able, from a rest situation in which the retaining ridge projects towards the axis of the collar relative to the edge of the first flank in the unclamped situation of the collar, to be elastically deformed to space the retaining ridge away from the axis of the collar.

摘要： A clamping system for connecting a first tube and a second tube, the clamping system including a collar which includes a belt able to be clamped around clamping surfaces of the first and second tubes, the belt has a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries at least one retaining loop disposed outside the belt. The loop has a first end fastened to the collar and a second end which is free and which is located on the outer side of the first flank. The loop is able to adopt a position of active retaining configuration in which its second end protrudes towards the axis of the collar relative to the edge of the first flank, and to be deformed relative to this active configuration so that the second end is moved radially outwardly.

摘要： The clamping collar comprises a metal belt carrying a protruding lug in the vicinity of a first end and a hook in the vicinity of a second end. The hook has a front wall and a common part. The wall is intended to be retained behind the lug while the hook is hooked on the lug to keep the collar in the clamped state. The common part links the front wall to the belt and has a gripping surface protruding radially outwardly and two lateral borders which extend axially on either side of the gripping surface by being radially set back from the gripping surface.

摘要： 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.

摘要： The collar has a metal belt (10), a pair of projecting lugs (12, 14), a tightening rod (16) disposed in holes in the lugs, and tightening members (16A, 16B) co-operating with the rod and with bearing portions of the lugs. At least one of the lugs in the pair is a lug (14) having an extension, the bearing portion of which lug is formed in an extension (17) of the lug, which extension is folded over towards the rear of the lug, and is provided with a hole for the tightening rod. The extension (17) and the front portion (15) of the lug (14) having an extension are interconnected via a strip portion (20) forming a link loop defining an axial tunnel having its two axial ends open, the tunnel being shaped so that the angle of inclination between the extension (17) and the front portion (15) of the lug can change when the collar is tightened.
