PURPOSE: To provide a variable staple that can correspond to the support of all F cables by employing a synthetic resin molding with both strong toughness and insulating property such as Delrin, making the connecting accommodation to and the automatic discharge from the staple easier, and making a bridge width flexible.

CONSTITUTION: Bridges 5a, 5b with suitably thinned peripheries 4a, 4b and a center 3 are disposed between stud upper portions 2a, 2b. An F cable is hold by studs 1a and 1b and pressed into a previously designed hole, thus being supported therein. All kinds of F cables can be held by enlarging or reducing the angle θ formed by the bridges 5a and 5b. As a consequence, the support of all kinds of F cables and other smaller cables for weak electric power can be performed by one kind of staples, thus the three-dimensional freedom in wiring operation is improved sharply due to the synergy of the directionality applying effects for attaining the support at a right angle and in parallel.
