Embodiment Construction

[0040] see figure 1 , it can be seen that the clamping collar 1 has a strap 10 with a lug 12 at a first end 10A and a hook 14 at a second end 10B. Shown here is the collar in the open state, with the hook not hooked on the lug and with the ends 10A and 10B spaced apart. It will be understood that the band defines a cylindrical circumference centered on the axis A when the collar is closed by the hook hooking on the lug.

[0041]Thus, in the example shown, the collar is of the "open" type and can be closed and clamped by hooking the hook over the lug. The following description refers to a particular type of hook which has no radial fold at its rear base. However, other types of hooks may be provided, in particular hooks provided with a folded portion at their rear base, eg as in patent application EP 0 636 826 .

[0042] Additionally, other closures are possible. For example, the collar may be of the tangential screw type, eg as in patent applications EP 0 305 232 , EP 2 58...

Abstract

The clamping collar comprises a metal belt (10) configured to be clamped on an object, the belt having an inner recess (20) comprising a bottom (23) delimited by cheeks (22, 24) oriented towards the axis of the belt, the collar having a capacity reserve (30), formed by a portion of the belt likely to elongate under the effect of a clamping tension of the belt, the capacity reserve being delimited,along the circumferential direction of the belt, by linking portions (36) in which the cheeks (22, 24) are interrupted and having cheek portions (32, 34) oriented towards the axis of the belt.

Description

technical field [0001] The present disclosure relates to a clamping collar comprising a metal strip configured to be clamped on an object, the strip having an inner groove having a bottom, the bottom Defined by cheeks oriented towards the axis of the belt. Background technique [0002] Such clamping collars are used to clamp objects such as pipes fitted on end pieces, or two pipe sections joined together end-to-end or by fitting. The object has an annular protrusion received in a groove of the band. The sides of this annular projection form bearing surfaces against which the cheeks defining the grooves abut when the object is clamped by the collar. This support promotes clamping security. For an object formed by two object parts (eg two pipe parts) that abut in a raised area, the support ensures this abutment. [0003] The clamping collar may be used in environments that are subject to significant temperature changes, for example, outdoors or in the engine compartment of...
