Quick splice connectors are a fast and easy way to splice an electrical circuit into an existing wire. Quick splice connectors utilize insulation displacement technology, meaning that no stripping of the wires is necessary. Simply insert The existing wire into the splice along with your second wire, squeeze down on the metal insert with a standard pair of pliers, and close the insulating flap. Quick splice connectors are used in automotive electrical applications, as well as commercial and industrial electrical wiring as well. Quick splices are rated for use up to to 300 volts.
