Multiple hold down and release device for restraining and releasing a payload (3) from a spacecraft (4), and methods to release a payload (3) from a spacecraft (4) and to install such a multiple hold down and release device. The device comprises:- a plurality of hold-down assemblies (19, Figure 3) placed on the periphery of the device, each one of them comprising a hold-down bracket (11, Figure 4) configured to be attached to the payload (3) and a hold-down support (20, Figure 4), both of them with conical mating surfaces (10, 10', Figure 4), each hold-down support (20) comprising at least one torsion spring (9, Figure 4) around an axis (17, Figure 4),- a plurality of pairs of connecting levers (5), each one of the connecting levers (5) comprising a first end (14, Figure 4) configured to be coupled to a corresponding hold-down support (20) such that each corresponding lever (5) is articulated with the corresponding hold-down support (20) through an axis (17); and a second end (15, Figure 4) opposite to the first end (14),- a plurality of restraint cables (6) that join the second ends (15) of each pair of connecting levers (5) and are arranged radially with a central area where the restraint cables (6) cross, and- a central release actuator (1) configured to be able to cut the restraint cables (6).
