DESCRIZIONE
The invention relates to a connection device (1) for connecting a compressed gas cylinder (5) to an inflatable device (9), wherein the connection device (1) comprises a releaser (4) with an activation mechanism for controlled puncture of the compressed gas cylinder (5), wherein the connection device (1) further comprises: an outer sleeve (200) for being fastened into the releaser (4) by turning in a first direction; and an inner sleeve (100) for being fastened into the outer sleeve (200) by turning of the inner sleeve (100) in a second direction and for the compressed gas cylinder (5) to be fastened into said inner sleeve (100) by rotation of the compressed gas cylinder (5) in the first direction, wherein the connection device (1) is configured such that turning of the compressed gas cylinder (5) in the second direction will result in axial displacement and puncture of the compressed gas cylinder (5).
