Abstract

Device for internal gripping of an exhaust pipe having a gripping device which in turn has a first and a second protrusion, which are mutually connected to allow mutual displacement along a first axis (A), in which this displacement imposes a mutual change of position of the first and second protrusions along a second axis (B), perpendicular to the first axis. The device also has a manoeuvering device for achieving the mutual displacement of the two protrusions. The manoeuvering device comprises an advancement unit arranged to displace the first protrusion along the first axis (A) in relation to the manoeuvering device, and a connecting link, which connects the manoeuvering device to the second protrusion and which limits the displacement of said second protrusion along the first axis (A) relative to the manoeuvering device during the displacement of the first protrusion by the advancement unit.
