Abstract: The invention relates to a shut-off device comprising a plug intended to be placed over a threaded orifice of a casing, or to be removed therefrom, by screwing and unscrewing respectively, the plug comprising a central body bearing a screw thread, and locking and unlocking means that oppose the spontaneous unscrewing of the plug and that are activated automatically by the turning of the plug and its corresponding progression in the direction of screwing along a longitudinal axis. The locking and unlocking means comprise two releaseable coupling members, of which a first member is coupled to and turns with the central body via a protective skirt and of which a second member can be prevented from turning with respect to the casing during screwing.

Abstract: An obturating device including a body (11) with a recess (8) at one end engageable by a spanner, and a screw thread (2) at the other end for engaging a complementary screw thread (7) in an opening (6) of a housing (3). A locking ring (31) biased by a spring in the obturating device (1) and a complementary locking ring (47) in the opening have asymmetrical teeth which interlock when screwing-in is complete and snap together to prevent loosening of the rings. The tooth flanks that engage one another on loosening are nevertheless sufficiently angled to enable forced unscrewing using a spanner. A skirt (14) protects the mechanism and acts as an abutment in the fully screwed-in position. The obturating device enables locking and unlocking, requires no direct manual operation and is particularly suitable for endoscope insertion openings in aircraft engines.

Abstract: A nut is prevented from turning during screwing by a body attached to one of the parts to be tightened by rivets. The body prevents the nut from rotating via a ring coupled without clearance with the nut and coupled with radial clearance to the body, in order to allow the nut to self-position itself along the axis imposed on the screw by the bores traversed by the screw. The nut can thus be a standard nut or a floating cage nut. Application to the retaining of nuts that are inaccessible and/or require a high level of security against unintentional unscrewing.

Abstract: The device connects a first end-coupler with a second end-coupler, in particular of a piping. A nut is provided with a threaded bore in which the first end-coupler is screwed along a longitudinal axis. In a tightening position, the first end-coupler is in axial stress with a second end-coupler accommodated in the nut. Anti-rotation means are provided between the nut and at least one of the end-couplers to prevent relative rotation except when a torque exceeding a predetermined threshold is applied thereto. The anti-rotation means consist of at least one tab made in the material of the nut to lockingly interfere with substantially planar faces formed on the second end-coupler.

Abstract: A locking device (1) is fixed to a nut (4) and includes a coupling unit (42) insertable into a hexagonal configuration (11) of a spigot end (2) at a reduced axial distance being coupled by mutually interpenertratable gears (49, 51) with a stop unit (38) which axially sliding in a body (18) oppositely to a compression spring (36). The gears (49, 51) are symmetric and are insertable into each other with a predetermined elastic resistance by the action of compression or loosing torque. The device is embodied in one piece which is mounted by assembling with the nut without effecting the spigot ends (2, 3). The device is used for locking a coupling in a systematic manner and makes it possible to unlock it without any preliminary voluntary operation.
