A cargo bar intended to be fitted between a floor and a ceiling of a cargo space, the cargo bar comprising: a first section having a ceiling contacting portion, a second section having a floor contacting portion, the second section being telescopically displaceable with respect to said first section between a contracted position and an expanded position such that, when the cargo bar is arranged in a cargo space having a height corresponding to the height of the cargo bar, and the second section is brought into its expanded position, said ceiling contacting portion is brought into contact with the ceiling, an expansion biasing element connected to said first and second sections and adapted to bias said second section toward said expanded position, locking means including a locking pin displaceable in a direction transverse to a longitudinal extension of the cargo bar, said locking means having a locked position, in which the locking pin extends through respective openings (202, 203) of the first and second sections so as to lock said second section in said contracted position, and an open position, in which a displacement of said second section with respect to said first section is allowed, and a maneuvering mechanism including a rotatable lever arranged to longitudinally displace said second section toward said contracted position, when said lever is rotated in a first direction, characterized in that the maneuvering mechanism further comprises an actuating member connected to the lever, wherein the rotating lever is arranged to longitudinally displace the actuating member along the longitudinal extension of the cargo bar, wherein said actuating member is adapted to interact, when said lever is rotated in a second direction opposite said first direction, with an abutment surface of the locking means to bring the locking means from the locked position to the open position, thereby releasing the second section and bringing the second section into its expanded position by action of the expansion biasing element, and wherein the actuating member comprises a wedge adapted to interact with said abutment surface to convert a longitudinal displacement of the actuating member to a transversal displacement of the locking pin. a first section having a ceiling contacting portion, a second section having a floor contacting portion, the second section being telescopically displaceable with respect to said first section between a contracted position and an expanded position such that, when the cargo bar is arranged in a cargo space having a height corresponding to the height of the cargo bar, and the second section is brought into its expanded position, said ceiling contacting portion is brought into contact with the ceiling, an expansion biasing element connected to said first and second sections and adapted to bias said second section toward said expanded position, locking means including a locking pin displaceable in a direction transverse to a longitudinal extension of the cargo bar, said locking means having a locked position, in which the locking pin extends through respective openings (202, 203) of the first and second sections so as to lock said second section in said contracted position, and an open position, in which a displacement of said second section with respect to said first section is allowed, and a maneuvering mechanism including a rotatable lever arranged to longitudinally displace said second section toward said contracted position, when said lever is rotated in a first direction, characterized in that the maneuvering mechanism further comprises an actuating member connected to the lever, wherein the rotating lever is arranged to longitudinally displace the actuating member along the longitudinal extension of the cargo bar, wherein said actuating member is adapted to interact, when said lever is rotated in a second direction opposite said first direction, with an abutment surface of the locking means to bring the locking means from the locked position to the open position, thereby releasing the second section and bringing the second section into its expanded position by action of the expansion biasing element, and wherein the actuating member comprises a wedge adapted to interact with said abutment surface to convert a longitudinal displacement of the actuating member to a transversal displacement of the locking pin.
