The invention relates to an arrangement (206) for manually releasing nautical life saving equipment, e.g. containers for inflatable life rafts. The release arrangement (206) is located as a connecting link between a first rope arrangement (205) and a second rope arrangement (215) adapted to fixating the life saving equipment. The second rope arrangement (215) forms a loop (213) encircling the first rope arrangement (205). The first rope arrangement (205) is fixed to a connecting stick (207) so that the connecting stick (207) together with the first rope arrangement (205) forms a stop preventing the loop (213) of the second rope arrangement (215) to run along the first rope arrangement (205). The connecting stick (207) is adapted, at release, to turn around an axis formed by the loop (213) of the second rope arrangement (215). The axis is orthogonal to the longitudinal axis of the rope arrangements. The force needed to release the arrangement (206) is rather independent of the tension forces in the rope arrangements (205, 215).
