Abstract: A connector (1) and a system for interconnecting tubular profiles. The connector comprises first and second connector ends (2, 3), an intermediate part (4) arranged between the connector ends (2, 3). A first engaging element (5) is movably arranged relative a second engaging element (6), between a non-expanded state and an expanded state of the connector (1). An expansion bracket (7) comprises a distal part (8) arranged at a first distance (a) from the intermediate part (4) and at least one proximal part (9) arranged at the intermediate part (4). A tensioner (10) is arranged at the intermediate part (4) and substantially extending in a transverse second axis direction (Y) relative a first longitudinal axis direction (X) of the connector (1).

Abstract: Bracket (1) for supporting a wall element (50) between two posts (60) and a system for shielding an area. The bracket (1) which is tube-shaped and arranged to enclose a post (60) comprises a front part (2), a back part (3), and first and second side parts (4, 5). At least one of the first and second side parts (4, 5) comprises a slit (6) with a receiving section (6a) open towards the front part (2) and arranged for receiving a protrusion (51) of a wall element (50). The slit (6) comprises a locking section (6c) for keeping a protrusion (51) of a wall element (50) in a locked position, and is arranged at a first distance (a) from the receiving section (6a) in a first direction (X1) of the bracket (1). The slit (6) comprises a guiding section (6b) arranged between the receiving section (6a) and the locking section (6c) which is arranged for guiding a protrusion (51) from the receiving section (6a) to the locking section (6c).

Abstract: In a device for attachment of a surface shaped wall element between two upright poles which have two positions for the wall element, an unstable readiness position and a locked position, at least one encircling mounting is provided on each pole for support of the wall element.

Abstract: In a system for screening off an area, a partition element substantially covers the space between two upstanding carrier elements. The partition element is catchable in the carrier elements in a temporary, unstable preparatory position. The partition element lacks the capability of remaining in the preparatory position by its own force. The partition element is further movable from the preparatory position to a fixedly locked position in the carrier elements. In a method of mounting and dismounting of a partition element on two upstanding carrier elements, the partition element is hooked in the carrier elements in the preparatory position. Thereafter, the partition element is moved to a fixedly locked position in the carrier elements.
