Abstract: Mounting and retaining apparatus for electrical, optical, or fluid conductors has a pair of resilient top members cantilevered from relatively rigid vertical sidewalls which are attached to a relatively rigid horizontal base member. The apparatus defines a rectangular channel in which the conductors are housed. The apparatus is adapted to allow conductors to be easily inserted into or removed from the channel via a one-hand operation. Insertion is accomplished by placing a conductor over the top members and pushing down on them so as to cause an opening between the top members which is sufficient to allow the conductors to enter the channel. The resilient top members may overlap to hide the conductors retained in the channel or they may be spaced apart.
