A display device (1), which has a pair of rotatable rollers (2 and 3) in substantially spaced apart relationship. The rollers (2 and 3) are adapted t o receive a carrier (4). In order to remove, replace, or install the carrier (4), at least one of the rollers is supported on a displaceable axle (14) which is movable between an operational position (Fig. 5(a)) when the carrie r (4) is tightly tensioned, and a replacement position (Fig 5(b)), when the carrier (4) is slack and can be easily removed from the rollers (2 and 3). A tool (22) may be used to assist movement of the axle (14) in the J-shaped sl ot (13).
