The present invention relates to a non-corrugated protective tubular housing for electrically and non-electrically conducting elongated members. The non-corrugated protective tubular housing can include a tubular body extending along a longitudinal axis that defines a length between a first end and a second end and defining a hollow volume, where at least one of the first and second ends is an open end; and a slit extending along the longitudinal axis and over at least a portion of the length between the first and second ends. The present invention also relates to a method having the step of housing the electrically conducting elongated member within the non-corrugated protective tubular housing.
