A manually-operated shrink-wrap device is described. The device includes a rigid support member having first and second sections, a handle at the first section, and a flexible leash attached to the second section. The rigid support member is adapted to support a film roll, and to facilitate rotational dispensing of film from the film roll to wrap the target load, which is typically a palletized load. The device also typically includes upper and lower film roll engagements for holding the film roll therebetween. A tensioning member may provide tension to the film roll along the longitudinal axis of the support member upon movement of one of the film roll engagements towards the tensioning member.

The single-reel tape cartridge as claimed in claim 1, wherein the leader member comprises a leader pin and a hooking arm connected to each of opposite ends of the leader pin so as to extend generally perpendicular to the leader pin, the hooking arms on the respective ends of the leader pin being cooperable with the catch member when the length of magnetic tape is to be drawn out of the cartridge housing.3. The single-reel tape cartridge as claimed in claim 2, wherein the second locking member comprises an elongated lock body reciprocatingly displaceably supported by the cartridge housing, and a separate biasing spring housed within the cartridge housing for urging the elongated lock body in a direction required for the elongated lock body to engage the leader pin.4. The single-reel tape cartridge as claimed in claim 2, wherein said bearing boss is journalled by and within the cartridge housing for angular movement about its own longitudinal axis, said second locking member further comprising an elongated lock body formed integrally with the bearing boss so as to extend in a first direction generally perpendicular to the longitudinal axis of the bearing boss, and a lock release piece formed integrally with the bearing boss so as to extend in a second direction counter to the first direction, said elongated lock body applying a retaining force to the leader pin to lock the leader pin at the retracted position in cooperation with the first locking members.5. The single-reel tape cartridge as claimed in claim 2, wherein the second locking member further comprises an elongated lock body formed integrally with the bearing boss so as to extend in a first direction generally perpendicular to the bearing boss, said elongated lock body including at least one lock arm having a free end thereof bifurcated to define a pair of elastically deformable embracing pieces for receiving the leader pin therein, and at least one receiving arm having a free end thereof formed with a hook for holding the leader pin, and wherein a direction of detachment of the leader pin relative to the lock arm and a direction of detachment of the leader pin relative to the receiving arm lie at an angle to each other.6. The single-reel cartridge as claimed in claim 2, wherein the second locking member further comprises an elongated lock body formed integrally with the bearing boss so as to extend in a first direction generally perpendicular to the bearing boss, said elongated lock body including a pair of receiving arms for engagement with opposite ends of the leader pin in a direction outwardly of the cartridge housing and a lock arm for receiving a portion of the leader pin intermediate between the opposite ends thereof.7. The single-reel tape cartridge as claimed in claim 2, wherein the cartridge housing also has a pivotally supported door for selectively closing or opening the tape window and has an inner side face leading towards an interior of the cartridge housing, said inner side face of the door being configured to retain the leader pin at the retracted position when the door is in position to close the tape window.8. The single-reel tape cartridge as claimed in claim 1, wherein the second locking member further comprises an elongated lock body formed integrally with the bearing boss so as to exte
