Abstract: A protective shroud (22) for a flexible electrical cable (20) at the location where it emerges coaxially from the rear end (14) of an electrical device, such as an inductive proximity or photoelectric sensor (2), serving as a strain relief and protection from being bumped as well as retaining such electrical cable (20) at a gradual right-angle bend from a horizontally-mounted sensor (2) to keep it out of the way, such as from the aisle adjacent a conveyer on which the sensor is mounted. Snap-in means including an annular groove (18) on the rear end of the sensor (2) and a constricted-opening (22f) slot (22e) in the inner side wall (22d) of the shroud (22) afford snap-in mounting of the latter onto the rear end (14) of the sensor (2) with the shroud (22) being rotatable thereon to allow the electrical cable (20) to be oriented in any desired direction. Another version of protective shroud (24) adapted for a vertically-mounted sensor ( 2) in FIG.
