A stabilizer (1) for a link of a three-point suspension system of an agricultural tractor has at least one telescope (8) consisting of a tube (5) and a piston (6). Said tube and piston are coupled elastically by at least one spring (7) and can be adjusted in length by means of threads (12, 13). At least one retaining clip (15) which can engage over an abutment (17) is held pivotably on the tube (5). To increase the load-bearing capacity of the stabilizer (1), the stop surfaces (18) of the retaining clip (15) are connected in a tensionproof manner by means of at least one bridge (30). Said bridge (30) engages over the outer side of at least one contact surface of the abutment (17) by means of the stop surface (18).
