Abstract: A locking member has a first surface, a first mounting opening and a second mounting opening. Each first mounting opening and second mounting opening is dimensioned to receive the shank portion of a corresponding rotatable member therethrough so that a bottom surface of a head portion of the rotatable member faces toward the first surface of the locking member. A first extending member extends elastically relative to the first surface, wherein the first extending member is disposed in close proximity to the first mounting opening. When the rotatable member is in a mounting position in the first mounting opening, the first extending member contacts the head portion of the rotatable member to inhibit the rotatable member from rotating in a first direction, and the first extending member deflects elastically when the rotatable member rotates in a second direction opposite the first direction.

Abstract: A ratchet nut assembly includes an inner member, an outer member, and a spring clip. The inner member includes an outwardly extending tooth. The outer member is positioned around a portion of the inner member and includes an inwardly extending pawl. The pawl is engageable with the tooth to rotate the inner member with the outer member in a first direction when a torque applied to the outer member is below a predetermined value and is operable to deflect outwardly to allow rotation of the outer member relative to the inner member in the first direction when the torque applied to the outer member is above the predetermined value. The pawl is engageable with the tooth to prevent rotation of the outer member relative to the inner member in a second direction. The spring clip is positioned around a portion of the outer member to limit deflection of the pawl.

Abstract: A wheel lug nut locking device having first and second planar sections, each with an opening adapted to be fitted around a wheel lug nut. The planar sections are connected by a flexible section that allows the planar sections to be moved relative to one another. In a preferred embodiment, the flexible section has a concertina-like structure. In use, the locking device is used to lock a wheel lug nut to an adjacent wheel lug nut, so as to prevent or reduce rotation of the wheel lug nut. A plurality of locking devices can be fitted to a single wheel so that all of the lug nuts are operatively locked to an adjacent lug nut. The resulting locking system can be rapidly installed on each lug nut on all wheels, so as to provide improved safety aspects.

Abstract: An engagement fitting attaches to a rotational fastener, and is anchored to a point stationary relative to the fastener. A rotational coupling attaches the engagement fitting to an anchor member, allowing uni-directional rotation of said engagement fitting on the rotational fastener, relative to the anchor member, about the fastener axis, in a loosening direction of said rotational fastener, to prevent self-loosening of the fastener.

Abstract: An anti-unscrewing device for coupling the tubular ends of two components in fluid conveying or delivery systems by means of a threaded ring nut that can be screwed to one of said tubular ends to connect said ends, wherein said anti-unscrewing device comprises a connecting portion to connect the device to one of the components and at least one counter element provided with an engaging portion suitable to engage a corresponding engaging surface formed at said ring nut, such that the engaging portion can be displaced by means of a movement of the ring nut. There are further provided guide means dictating a movement path for the counter element, such that an unscrewing movement of the ring nut will cause the engaging portion to move to a locking position relative to the ring nut thereby preventing the ring nut from unscrewing.

Abstract: A wheel locking assembly for preventing theft of wheels and tires. The wheel locking assembly includes a wheel rim assembly including a disc-shaped wheel rim having a first side and a second side, and also having an axle-receiving opening being centrally disposed therethrough, and further having fastener holes being spaced apart and being disposed therethrough, and also having cover-mounting holes being disposed therethrough; and also includes a fastener assembly including fasteners being lockingly disposed in the fastener holes of the disc-shaped wheel rim; and further includes a locking assembly being disposed in the disc-shaped wheel rim for locking the fasteners in the fastener holes; and also includes cover members being fastenably attached to the wheel rim.

Abstract: An attachment system, which is to be introduced in a mounting opening (5) of a hollow body (3), includes a rear engagement member (4) for engaging from behind holding projection (17.1, 17.2) of the hollow body (3), at least one stop (6, 37) for engaging edges of outer sides of the hollow body which limit the mounting opening (5) and connected with the rear engagement member (4) by a screw, and a device providing for a relative rotational movement between the stop (6) and the rear engagement member (4) about an axis of the fastening means (7; 35) and formed as a transformation device (9; 31) for converting a translational movement of the screw (7; 35) relative to the stop (6) in a rotational movement of the rear engagement member (4) relative to the stop.
