A device for securing an object to a ceiling, comprising: a lead screw having a longitudinal axis about which the lead screw rotates; and a spring-loaded tab comprising: a carriage that is coupled to the lead screw such that the carriage is displaceable along a length of the lead screw via rotation of the lead screw; and a leg including a first end that is coupled to the carriage, and a second, free end; and a spring biasing the free end of the leg outwardly, away from the object into a deployed position, the leg being rotatable about a pivot axis, wherein, the device is suitable to be attached to the object and configured such that when the object with the device attached to it moves in a first direction through a hole in the ceiling such that the leg contacts an edge of the hole, the leg is urged from the deployed position toward a retracted position, and wherein when the object is further moved in the first direction such the leg is clear of the hole, the leg returns to the deployed position via a force applied by the spring, and wherein the leg comprises an angled surface configured to engage the edge of the hole to urge the leg toward a retracted position as the object moves in the first direction through the hole, wherein the device further comprises a retraction plate to be secured to the object so as to form a pocket therebetween, wherein, when the lead screw is rotated to drive the spring-loaded tab toward a top end portion of the object, the retraction plate is configured to engage the angled surface to urge the leg into the retracted position within the pocket, said device being characterised in that the leg is coupled to to the carriage such that there is no relative movement between the leg and the carriage, and in that the pivot axis of the leg is coincident with the longitudinal axis of the lead screw. a lead screw having a longitudinal axis about which the lead screw rotates; and a spring-loaded tab comprising: a carriage that is coupled to the lead screw such that the carriage is displaceable along a length of the lead screw via rotation of the lead screw; and a leg including a first end that is coupled to the carriage, and a second, free end; and a spring biasing the free end of the leg outwardly, away from the object into a deployed position, the leg being rotatable about a pivot axis, a carriage that is coupled to the lead screw such that the carriage is displaceable along a length of the lead screw via rotation of the lead screw; and a leg including a first end that is coupled to the carriage, and a second, free end; and a spring biasing the free end of the leg outwardly, away from the object into a deployed position, the leg being rotatable about a pivot axis, wherein, the device is suitable to be attached to the object and configured such that when the object with the device attached to it moves in a first direction through a hole in the ceiling such that the leg contacts an edge of the hole, the leg is urged from the deployed position toward a retracted position, and wherein when the object is further moved in the first direction such the leg is clear of the hole, the leg returns to the deployed position via a force applied by the spring, and wherein the leg comprises an angled surface configured to engage the edge of the hole to urge the leg toward a retracted position as the object moves in the first direction through the hole, wherein the device further comprises a retraction plate to be secured to the object so as to form a pocket therebetween, wherein, when the lead screw is rotated to drive the spring-loaded tab toward a top end portion of the object, the retraction plate is configured to engage the angled surface to urge the leg into the retracted position within the pocket,
