A cover assembly for covering an elongate substrate includes a holdout device and a resilient, elastically radially expanded sleeve member. The holdout device includes a core having an axially extending slit defined therein and defining a core passage to receive the substrate, and a designated target region. The sleeve member defines an axially extending sleeve passage. The sleeve member is mounted on the core such that the core is disposed in the sleeve passage and the sleeve member exerts a radially compressive recovery force on the core. When the substrate is disposed in the core passage and a radially directed release force is applied to the target region, the core will reduce in circumference and collapse around the substrate under the recovery force of the sleeve member to a collapsed position.

1. A cover assembly for covering an elongate substrate, the cover assembly comprising: a holdout device including: a core having an axially extending slit defined therein and defining a core passage to receive the substrate; anda designated target region; anda resilient, elastically radially expanded sleeve member defining an axially extending sleeve passage, the sleeve member being mounted on the core such that the core is disposed in the sleeve passage and the sleeve member exerts a radially compressive recovery force on the core;wherein, when the substrate is disposed in the core passage and a radially directed release force is applied to the target region, the core will reduce in circumference and collapse around the substrate under the recovery force of the sleeve member to a collapsed position;wherein the release force applied to the target region causes an axially extending first edge of the core to slide beneath an opposing axially extending second edge of the core, thereby allowing the core to curl upon itself under the recovery force; andwherein the holdout device includes an access opening defined therein and the target region is exposed through the access opening for application of the release force. 2. The cover assembly of claim 1 wherein the second edge defines an axially extending ledge. 3. The cover assembly of claim 1 wherein: the core includes an axially extending edge section adjacent the slit and an axially extending flange overlapping the edge section;the target region is located on the edge section; andthe access opening is defined in the flange. 4. The cover assembly of claim 3 wherein: the core includes a body member and a separately formed retention member mounted on the core;the flange forms a part of the retention member; andthe access opening is defined in the retention member. 5. The cover assembly of claim 1 wherein the first edge is circumferentially loaded against the second edge by the recovery force, thereby creating a frictional resistance to disengagement between the first and second edges that is overcome by applying the release force to the target region. 6. The cover assembly of claim 5 wherein: the first edge includes an engagement edge portion and a recessed edge portion;the engagement edge portion engages the second edge; andthe recessed edge portion is circumferentially spaced apart from the second edge. 7. The cover assembly of claim 6 wherein the target region is located axially proximate the recessed edge portion. 8. The cover assembly of claim 1 including a status indicator to indicate to a user whether the core is in a retaining position or, alternatively, a collapsed position. 9. The cover assembly of claim 8 wherein the status indicator includes a color indicator. 10. The cover assembly of claim 1 including an integral, removable safety rail mounted on the core, wherein the safety rail is configured to prevent collapse of the core until the safety rail is removed, and to thereafter be used to apply the release force to the target region. 11. The cover assembly of claim 1 wherein the axially extending slit extends the full length of the core and radially completely through a wall of the core. 12. A cover assembly for covering an elongate substrate, the cover assembly comprising: a holdout device including a core having an axially extending slit defined therein and defining a core passage to receive the substrate; anda resilient, elastically radially expanded sleeve member defining an axially extending sleeve passage, the sleeve member being mounted on the core such that the core is disposed in the sleeve passage and the sleeve member exerts a radially compressive recovery force on the core;wherein: when the substrate is disposed in the core passage and a radially directed release force is applied to the holdout device, the core will reduce in circumference and collapse around the substrate under the recovery force of the sleeve member to a collapsed position;the release force applied to the holdout device causes an axially extending first edge of the core to slide beneath an opposing axially extending second edge of the core, thereby allowing the core to curl upon itself under the recovery force;the first edge is circumferentially loaded against the second edge by the recovery force, thereby creating a frictional resistance to disengagement between the first and second edges that is overcome by applying the release force to the holdout device;the first edge includes an engagement edge portion extending along a first axial extent of the first edge and a recessed edge portion extending along a second axial extent of the first edge different from the first axial extent;the engagement edge portion engages the second edge and is circumferentially loaded against the second edge by the recovery force; andthe recessed edge portion is circumferentially spaced apart from the second edge and defines a recess between the second edge and the recessed edge portion. 13. A cover assembly for covering an elongate substrate, the cover assembly comprising: a holdout device including: a core having an axially extending slit defined therein and defining a core passage to receive the substrate, the core being configured in a retaining position; anda status indicator; anda resilient, elastically radially expanded sleeve member defining an axially extending sleeve passage, the sleeve member being mounted on the core such that the core is disposed in the sleeve passage and the sleeve member exerts a radially compressive recovery force on the core;wherein: when the substrate is disposed in the core passage and a radially directed release force is applied to the holdout device, the core will reduce in circumference and collapse around the substrate under the recovery force of the sleeve member to a collapsed position from the retaining position; andthe status indicator is operative to indicate to a user whether the core is in the retaining position or, alternatively, the collapsed position. 14. The cover assembly of claim 13 wherein the status indicator includes a color indicator. 15. The cover assembly of claim 12 wherein: the holdout includes a designated target region;when the substrate is disposed in the core passage and a radially directed release force is applied to the target region, the core will reduce in circumference and collapse around the substrate under the recovery force of the sleeve member to the collapsed position; andthe target region is located axially proximate the recessed edge portion. 16. The cover assembly of claim 15 wherein the recess and the target region are located proximate a terminal axial end of the core. 17. The cover assembly of claim 16 wherein the recess extends axially from the engagement edge portion to the terminal axial end of the core. 18. The cover assembly of claim 12 wherein the recess extends axially from the engagement edge portion to a terminal axial end of the core.
