This includes wherein the bracket body includes one or more a pull buckles and slide grooves, and slide plates, such that the body can be released and opened to either to unlock and remove or insert and lock two disparate plugs to be connected. ## Claims ### Claim 1 An adjustable plug and socket anti-unlocking device, comprising: a body, wherein the body is made of at least a base and bracket coupled together, wherein: the base is configurable with: a base buckle at a first end of the body, wherein the base buckle pivots at a pivot point in the base, one or more slide shafts and slide pins, wherein the slide pins are inserted through the slide shafts and are held captive; the bracket is configurable with: a bracket buckle at a second end of the body, opposite to the first end, wherein the bracket buckle pivots at a pivot point in the bracket, one or more slide slots, wherein the slide pins, inserted into the slide shafts in the base, are configured to pass through the one or more slide slots in the bracket, such that the bracket can slide up and down respective to the base and are held captive by the slide pins and respective slots; an open space interior of the body, wherein two wires or cords with respective plug or socket are able to be held. ### Claim 2 (depends on 1) A device as in claim 1, wherein the base and bracket buckle are able to be pivoted via the pivot point to be in an open or closed configuration. ### Claim 3 (depends on 2) A device as in claim 2, wherein the open configuration allows the two wires or cords with respective plug or socket are able to be inserted or removed. ### Claim 4 (depends on 2) A device as in claim 2, wherein the closed configuration disallows the two wires or cords with respective plug or socket to be disconnected such as from a yank or pull. ### Claim 5 (depends on 1) A device as in claim 1, wherein the bracket is configured to be adjusted via the one or more slide slots, shafts and pins such that the distance of the open space interior of the device fits the two cords or wires with a respective plug or socket to be held. ### Claim 6 (depends on 1) A device as in claim 1, wherein the base includes one or more ramps with saw teeth, wherein one or more tabs on the bracket are configured to interact with the saw teeth. ### Claim 7 (depends on 6) A device as in claim 6, wherein the length of the body, made of at least the base and bracket is adjusted via sliding the bracket, which is held captive to the base by the one or more slide pins via the slide shafts and wherein then the ramp saw teeth and tabs lock the length in place. ### Claim 8 (depends on 7) A device as in claim 7, wherein wherein the one or more tabs are configured to be manipulated by a user to unlock from the teeth. ### Claim 9 (depends on 6) A device as in claim 6, wherein wherein the saw teeth have a clearance angle α ranging from 70° to 90°. ### Claim 10 (depends on 6) A device as in claim 6, wherein wherein the saw teeth have a receding angle α is 80°. ### Claim 11 (depends on 1) A device as in claim 1, wherein the base buckle and bracket buckle include a buckle recess respectively, wherein the buckle recess is where the pivot point is configured the buckle includes two pivot extrusions, such that the extrusions fit in a pivot recess in the buckle recess on the respective body or bracket, such that each buckle can be removably connected to a respective bracket or body via the extrusions and recess. ### Claim 12 (depends on 1) A device as in claim 1, wherein the base and bracket buckle pivot range of motion is limited by the buckle recess, but wherein the buckles are able to be configured to close completely and open completely, such that a wire and cord are able to be inserted and removed from the device. ### Claim 13 (depends on 1) A device as in claim 1, wherein the base and bracket buckle includes two pivot extrusions, such that the extrusions fit in a pivot recess on the respective body or bracket, such that each buckle can be removably connected to a respective bracket or body via a pivot. ### Claim 14 (depends on 1) A device as in claim 1, wherein the base and bracket buckles are removable via a press fit. ### Claim 15 (depends on 1) A device as in claim 1, wherein the base and the bracket each include a crescent shaped open recess at each long end opposite each other when connected; the base buckle and the bracket buckle each include a crescent shaped open recess, such that when the buckles are connected to the respective base or body, and when the buckles are in a closed position, the crescent open recesses form a channel for the wire or cord to be held, such that the wire or cord does not get damaged. ### Claim 16 (depends on 1) A device as in claim 1, wherein the base and bracket buckles pivot in opposite directions such that the user is able to easily open the buckles. ### Claim 17 (depends on 1) A device as in claim 1, wherein configured on the base below the slide shafts and pins is a rotation notch, wherein the rotation notch aids in inserting and connecting the base and the bracket together via the sliding shaft, pin and slot, such that the bracket can be rotated in the range allowed by the notch. ### Claim 18 (depends on 1) A device as in claim 1, wherein the base and the bracket are symmetrical wherein the respective one or more sliding shafts, pins, slots and notch are symmetrical, such that the base and the bracket when viewed from the top or bottom include on each symmetrical side a matching slot, shaft pin and notch, such that between the symmetrical sides is the open space interior of the body. ### Claim 19 (depends on 6) A device as in claim 6, wherein the base and the bracket are symmetrical wherein the respective saw teeth ramps and tabs are symmetrical, such when viewed from the top or bottom include on each symmetrical side the saw teeth ramp and tab, such that between the symmetrical sides is the open space interior of the body. ### Claim 20 (depends on 1) A device as in claim 1, wherein the wires or cords with plug or socket is a standard NEMA connector.
