SUBSTANCE: fastener with remote control for detachable connection of structural elements with the longitudinal axis and with a fastening body for inserting into the fastening base. The fastening body comprises an anchor inserted into the fastening base, which moves at least in the first direction for fixing with the geometric and/or frictional locking of the fastener in the fastening base and in the second direction opposite to the first direction, for detaching it. The anchor is connected to a remote-controlled drive provided for the operation by means of a fluid, that is arranged in the fastener and moves to the second direction, the anchor comprising at least two separate parts and extending in a direction radial to the first direction, into which each of these separate parts moves, from the longitudinal axis. Each of these separate parts comprises a projection extending vertically to the longitudinal axis, which is made with the possibility to cooperate with providing the geometric locking with the undercut of the fastening base.

EFFECT: shortening the fastener detaching time.
