An arrangement for securing a synthetic-binding fitted coil to a sector of a covering plate having a seating place to receive a downward turning supporting surface of said coil with a securing means having a principal body mountable to the fitted coil, a supporting element in a movable position in relation to said body towards a transverse direction in relation to the covering plate for attraction to this plate and supporting thereto; also a fastening screw secured by a transverse to the covering plate thread of the principal body in order to press the supporting element against the covering plate where in order to reduce the manufacturing cost on the lower part of the coil opposite to a lying peripheral surface at least one groove is foreseen crossing almost in parallel to the covering plate. The principal body of the supporting element has a projection for penetrating said groove in order to secure the supporting element to the fitted coil. |
