An attachment system for a wearing point on a plough share includes a wearing point forming one of a connection socket and a connection pin, and a holder configured to receive the wearing point and to be fixed to the plough share. The holder forms an other of the connection socket and the connection pin. The connection pin and the connection socket are provided with complementary, cooperating guide portions. The holder is provided with a first bolt-hole group and a second bolt-hole group. The first bolt-hole group is complementary to an attachment-hole group of a left-hand plough share, and the second bolt-hole group is complementary to an attachment-hole group of a right-hand plough share.

A locking device (3) for a wearing part (2) detachably attached to a soil-working working element (1) by means of quick-coupling elements (11, 21), wherein a locking element (31) attached to the working element (1) includes an end portion (312) projecting from the working element (1) and being provided with an engagement section (313) arranged to engage with a lock-receiving element (22) arranged on a lee-side face (2a) of the wearing part (2).

The invention relates to a landside for use with a plow, wherein the landside has a landside body having a diverting face, a rear face opposite from the diverting face and an underside connecting the diverting face and the rear face, wherein the landside body has wear-protection element mounts, in which wear-protection elements made of hard material are mounted. A simple design, cost-effective manufacturability and high wear resistance are achieved by the wear-protection element mounts being incorporated into the underside and by the wear-protection elements being designed as pins.
