Electrical plug with a cable fastener

An electrical plug for electrically operated devices, the electrical plug comprising:

• a wire receiver including a hook having an elongated arm, the hook hanging into a cavity of an electrical contact holder, said cavity corresponding with a curvature of the hook, and a line connector adjacent to the cavity, wherein the elongated arm is configured to rotate the hook thereby causing the hook to be inserted into the cavity pressing against the line connector;
• said wire receiver configured to receive a wire between said hook and an electric contact held in said electrical contacts holder;
• a plug cover configured to cover said electrical contact;
• a cable fastener connected to said electric contacts holder, said cable fastener configured to receive an end of a cable containing said wire;
• a locking and unlocking mechanism for securing the plug cover to the electrical contact holder;
• a plurality of passages and slopes within a holder body, said holder body having at least a main passage, a locking slope adjacent to a first end of said main passage;
• an unlocking slope including an exit passage leading to the main passage located adjacent to said locking slope;
• an elongated arm having a tooth, said arm configured for passing through the main passage of the holder body, wherein said tooth is configure to engage said locking slope, thereby locking said tooth behind the locking slope adjacent to the unlocking slope;
• at least one lateral side of said tooth comprises a first, generally flat portion and a second, generally angled portion;
• a plurality of elongated springs matching the surface of the holder body, wherein a first extreme of each elongated spring is joined to the holder body and a second extreme rejecting the electrical contact holder;
• and a barrier within the holder body, said barrier adjacent to the locking slope, said barrier blocking the first portion of the lateral side of the tooth.
