Apparatus and associated methods relate to a shapeable conduit. In an illustrative example, the shapeable conduit may have a circumferentially flexible wall extending along a longitudinal axis. The wall may, for example, define a lumen configured to receive one or more cables. Multiple longitudinally extendable manually deformable axial stiffening members may, for example, be circumferentially distributed in the wall. A releasable coupling mechanism may, for example, have at least two mating engagement members. The engagement members may, for example, releasably engage in an enclosed state such that the wall circumscribes the lumen. The engagement members may, for example, be tangentially separable into an open state such that the cables can be radially transferred between an interior and an exterior of the lumen. Various embodiments may advantageously be manipulated such that the axial stiffening members cause the flexible wall to retain cables enclosed within the lumen in a desired configuration.
