A connection system adapted for removably attaching a deck to a support device of the deck, the connection system being characterized in that it comprises: - a plurality of mounts (1.1) arranged in a radial manner such that each mount is positioned at the same distance with respect to a center on the face of the support device configured for contacting with the deck; - a first set of apertures (1.2) spaced in a circular manner and arranged in a radial manner complementary to that of the mounts (1.1), configured for receiving the plurality of mounts (1.1) of the support device, and a second set of elongate apertures (1.3) spaced in a circular manner and arranged such that each one covers a sector of the circle that is formed, the first set of apertures (1.2) and the second set of elongate apertures (1.3) being separated in a concentric manner in a cavity (2.1) of the deck; and - a substantially circular actuation mechanism (1.4), comprising: o a plurality of retaining pins (1.4.1) arranged in a radial manner and configured for being introduced in the plurality of mounts (1.1) of the support device, and o a plurality of headed studs (1.4.2) which project perpendicular to the plurality of retaining pins (1.4.1) through one of the surfaces of the actuation mechanism (1.4), the plurality of headed studs (1.4.2) being configured for being introduced in the second set of elongate apertures (1.3) of the deck; such that the deck can be attached to or removed from the support device by means of turning the actuation mechanism (1.4). - a plurality of mounts (1.1) arranged in a radial manner such that each mount is positioned at the same distance with respect to a center on the face of the support device configured for contacting with the deck; - a first set of apertures (1.2) spaced in a circular manner and arranged in a radial manner complementary to that of the mounts (1.1), configured for receiving the plurality of mounts (1.1) of the support device, and a second set of elongate apertures (1.3) spaced in a circular manner and arranged such that each one covers a sector of the circle that is formed, the first set of apertures (1.2) and the second set of elongate apertures (1.3) being separated in a concentric manner in a cavity (2.1) of the deck; and - a substantially circular actuation mechanism (1.4), comprising: o a plurality of retaining pins (1.4.1) arranged in a radial manner and configured for being introduced in the plurality of mounts (1.1) of the support device, and o a plurality of headed studs (1.4.2) which project perpendicular to the plurality of retaining pins (1.4.1) through one of the surfaces of the actuation mechanism (1.4), the plurality of headed studs (1.4.2) being configured for being introduced in the second set of elongate apertures (1.3) of the deck; o a plurality of retaining pins (1.4.1) arranged in a radial manner and configured for being introduced in the plurality of mounts (1.1) of the support device, and o a plurality of headed studs (1.4.2) which project perpendicular to the plurality of retaining pins (1.4.1) through one of the surfaces of the actuation mechanism (1.4), the plurality of headed studs (1.4.2) being configured for being introduced in the second set of elongate apertures (1.3) of the deck;
