Abstract: The disclosure relates to a pivotable connection device (100) comprises a first and a second bracket (101, 102), a locking member (103), a spring (105), and an abutment member (104). The first and the second bracket (101, 102) are pivotable connected to each other, and the spring (105) is located between the locking member (103) and the abutment member (104). In a first mode of operation (M1), the locking member (103) is displaced towards the abutment member (104) such that the spring (105) is compressed, and such that the first and second bracket (101, 102) are pivotable in relation to each other. In a second mode of operation (M2), the locking member (103) is displaced towards the first bracket (101) by the spring (105), such that the locking member (103) overlaps the first and the second bracket (101, 102) and prevents pivoting. The disclosure further relates to a vehicle (200).
