摘要

Fixing element (1) comprises a drill head (5), and a cylindrical receiving body (2) having at the jigging direction end a holder for the drill head arrangement and at the opposite-lying end an engaging device. A single- or multi-component mortar composition preferably packed in a bag (28) is arranged in the receiving body. The fixing element is provided with at least one outlet opening (10.2) from which the mortar composition is applied by the pressure of a piston (27). A channel section (29) is provided between the mortar composition and the outlet opening. The mortar composition and the channel section are arranged in an inner tube (21) held by spacers a pre-defined distance between the outer wall of the inner tube and the inner wall of the receiving body to create at least one suction channel (22).
