Embodiment Construction

[0022] The device of FIG. 1 comprises a sleeve 10 in which a sealing ring 12 is arranged. This device is used to join together two smooth tubes arranged end-to-end and of substantially the same diameter in a leak-proof manner, which requires engaging the two opposite ends of the tubes into the ring 12 until the two opposite ends The end-to-end abutment protrusions 13 are adjoined on either side thereof. For reasons of convenience, the two tubes are not shown in Figure 1 , but reference is made to EP 1181477 for assembly details.

[0023] The sleeve 10 may be similar to that disclosed in EP 1181477 . It has a strip-like portion 10A and tensioning means arranged at its two opposite ends, between which a groove 11 is defined, the groove 11 being longitudinal, ie parallel to the axis of the sleeve. During tensioning, the width of the groove decreases, thereby reducing the diameter of the strip-like portion 10A accordingly.

[0024] However, in the preferred embodiment shown in ...

Abstract

The invention concerns a device comprising a sleeve (10), capable of being arranged around two opposite ends of the two tubes and provided with means for reducing its diameter under the action of clamping means (22, 24). The device comprises a sealing ring (12) arranged inside the sleeve (10) to enclose the ends of the tubes. Said ring consists of a band wound upon itself, whereof the ends bear at least one male / female assembly adapted to be urged to be engaged by contact upon clamping. At least one of the male and female configurations in the male / female assembly has contacting edges formed on the contact lugs (32A, 32B) adapted, upon engagement of the male configuration (28) into the female configuration (30) under the clamping effect to be folded in the direction promoting penetration of the male configuration into the female configuration.

Description

technical field [0001] The present invention relates to a device for joining together two smooth tubes arranged end-to-end and of substantially the same diameter in a leak-proof manner, the device comprising sleeves adapted to be positioned around the opposite ends of the two tubes, said The sleeve is provided with means capable of reducing the diameter of the sleeve under the action of a tensioning tool, the device further comprising a sealing ring adapted to be placed inside the sleeve and intended to surround the opposite ends of the two tubes, said ring Consists of a band that loops back on itself and has two ends adapted to form engaging contact by at least one male / female arrangement comprising a female portion and a male A ring inside the barrel is adapted to engage the male portion in the female portion when the sleeve is tightened around the opposite end of the tube. Background technique [0002] Devices of this type are known, for example from the applicant's pate...
