Abstract: A connection device for injecting a laser beam into an optical fiber is provided. The device includes two half grips for receiving one end of the optical fiber in a gripped position, a connector body for receiving the grips and for holding them in an optical fiber gripped position, and a conduction cooling mechanism for cooling the two half grips.

Abstract: This probe comprises a cable (4) and a probe head (6) fixed to one end of the cable and having an inspection head (18) provided with transmission-reception means (22, 24) for inspection signals from a tube (2), a support (20) on which the inspection head is mounted in rotary manner, a motor (66) for rotating the inspection head, an encoder associated with the motor for determining the circumferential extent of faults which the tube may have, and a rotary collector (10) between the motor and the support in order to ensure a mechanical connection between the motor and the inspection head and the transmission of control signals for the said means (22, 24) and signals supplied by the latter. Articulated mechanical connections (14, 16) are provided between the motor and the collector and between the collector and the inspection head.
