An explosive attachment device for mechanical connection of components, internally provided with an explosive charge, the detonation shock effect of which is strong enough for rupturing a connection forming part of the attachment device for a rapid disconnection, whereby the attachment device incorporates an attachment screw (2) and an explosive attachment element (4-14) which comprises a cylinder (4), a cover (5), and a piston (6) mounted in the cylinder (4), a space between the piston (6) and the bottom of the cylinder (4) is provided with a circular row of small holes (14), the piston (6) is provided with a rod (7) that the attachment screw (2) is mounted to, in the space between the piston and the cover (5) is arranged the explosive charge (9) with a firing device (10,11,12,13) having a delay mechanism, whereby the blasting pressure is converted to a pulling stress, which acts upon the attachment screw (2) to be pulled off without the other parts splintering.
