The elongated strap incorporates in inner side a plurality of teeth alternating with a plurality of grooves. The plurality of teeth extends from the first end up to a first no teeth zone located in proximity of the second end. A group of several teeth follows after the first no teeth zone. When wrapping the elongated strap, the buckle is kept in an indented retaining portion of the elongated strap with its several teeth projecting upwardly. After an adjustment of the elongated strap is completed, the buckle is so displaced that the several teeth penetrate corresponding grooves of the multiplicity of teeth.

  • Publication number: 20120115349
    Abstract: The present invention relates to a device used to maintain a plug and socket connection between two electrical cords. The device includes a pair of spaced-apart frustoconical members. Each frustoconical member has a passageway for receiving one of the cords and has a tapered exterior surface. Each frustoconical member has a pair of sides configured to guide the cord to its central passageway. The sides are angularly spaced-apart with respect to each other by an angle between 90 and 120 degrees, forming a channel therebetween. Each frustoconical member further has a pair of opposed recesses, between the inner and outer ends, with a space therebetween to facilitate insertion of its cord. Two elastic connecting members connect together the inner ends of the frustoconical members. The connecting members stretch over the plug and socket and bias the inner ends of the frustoconical members against outer ends of the plug and socket.
