Abstract: A clamping assembly constructed to hold an electrical cable or tube in a fixed position includes retaining and clamping members. A first surface of the retaining member, which may be made from a compliant material, has raised and lowered portions in a particular pattern. One end of the retaining member has a face transverse to the first surface of the retaining member with raised and recessed portions defining a mating relationship with the raised and recessed portions on the first surface of the retaining member. The clamping member may be made from a springlike material and may be disposed in an open loop in an unconstrained relationship. The clamping member may be disposed in a longitudinal slot in the retaining member so as to be encased by the retaining member. The retaining member may be slitted to communicate with the slot for facilitating the disposition of the clamping member in such slot.
