If you are happy with the direction your plant is growing, just leave as it is, it will be fine and grow normally despite the fractured stem. There is no need to bandage the fracture in any way - covering it with something is more likely to induce a mould or fungus to attack the break. Leave it to air dry and it will heal over with a crust and be perfectly fine. Trying to move it after leaving it for so long will likely cause more damage and is not recommended.
If this happens again in the future, using a splint attached with some soft wire or string above and below the break, and put in place within a few minutes of the break occurring can result in the break healing completely, allowing you to remove the splint after 2-3 weeks, checking that the stem can hold the weight before removing the splint entirely. A bamboo stake, skewer or wooded stick all make good splints, but once again, make sure not to cover the fracture when tying on the splint, the fracture needs to air dry and heal. I keep a selection of dried and various lengths and thicknesses of cannabis stems/branches from previous harvests for use as splints, should I have a need to use them in future grows. It is then simply matching the old stem size to the size of the fractured stem/branch.
High stress training can involve snapping stems and is very similar to fractures, and the plants do not seem to suffer in any way from this technique. Cannabis is a remarkably resilient plant and I have had tree branches fall on outdoor plants, doing many fractures and much damage, but after removing the tree branches and allowing a couple of days for the cannabis plant to sort itself out, have had them then grow and flower as though nothing ever happened to them at all.
