1. A protective sleeve assembly for protecting an electrical member and a wire harness extending therethrough, comprising:
a semi-rigid multi-layer tube extending longitudinally along an axis of the semi-rigid multi-layer tube between opposite ends of the semi-rigid multi-layer tube;
an end cap disposed over one of said opposite ends, the end cap having at least one finger that extends radially inward generally toward said axis, the at least one finger being resiliently flexible in opposite axial directions to allow assembly and disassembly of the protective sleeve assembly along the wire harness and about the electrical member; and
the semi-rigid multilayer tube including an inner tube and an outer tube, the inner tube having a semi-rigid tubular wall including radially extending energy dissipating features to minimize the transmission of impact forces to the electrical member, the outer tube being a textile tube disposed about the inner tube, the radially extending energy dissipating features including a plurality of radially outwardly extending ribs, the ribs including lengthwise extending ribs that extend generally parallel to said axis and circumferentially extending ribs extending between the lengthwise extending ribs to form a plurality of discrete pockets, wherein the discrete pockets form encapsulated chambers between the inner tube and the outer tube.
