摘要

Spacer comprises a through hole formed as a pressing seat hole which is lengthened in such a way that rounding of the inlet and outlet reaches the axial ends of a central piece. An independent claim is also included for a device (8) for applying several spacers on a reinforcing rod (7) comprising a delivery station (18) for introducing the rods. Preferred Features: The through hole has an annular bar close to each rounding. The middle piece has a round cross-section. A protruding guide is arranged on each side of a plate and has an outer contour delimited by the corners of a square.
