Connecting element for fastening a sink to a worktop, which worktop has a cutout for insertion of the sink, which cutout has a circumferential boundary surface, which connecting element has: a base body serving as an abutment part for abutment against the sink; a plurality of spring parts (3.1-3.8) projecting on a first side from the base body, which spring parts are configured to produce a spring force acting away from the base body when loaded in the direction of the base body; and at least one anchoring part (4.1-4.6) which projects from the base body on a second side thereof opposite the first side and which is configured to engage in a slot-shaped recess on the sink; in which an angle between an engagement direction of the anchoring part (4.1-4.6) and the direction of the spring force is at least 135 degrees, preferably at least 150 degrees, most preferably 180 degrees; in which the spring parts (3.1-3.8) are configured as tongues that project from the base body in an edge region of the base body and have a first partial extent (3.8a) adjoining the edge region and a second partial extent (3.8b) adjoining the first partial extent, the tongues extending in the first partial extent (3.8a) approximately perpendicularly to the base body and in the second partial extent (3.8b) approximately parallel, or at an acute angle of less than 45 degrees, preferably less than 30 degrees, to the base body; and in which the spring parts (3.1-3.8) have a further, third partial extent (3.8c) which adjoins the second partial extent (3.8b) and in which the spring parts (3.1-3.8) are angled away from the base body to a greater extent than in the second partial extent (3.8b); wherein the spring parts (3.1-3.8) differ from each other with regard to the angle between base body and tongue in the second partial extent (3.8b) and/or a length of the third partial extent (3.8c). a plurality of spring parts (3.1-3.8) projecting on a first side from the base body, which spring parts are configured to produce a spring force acting away from the base body when loaded in the direction of the base body; and at least one anchoring part (4.1-4.6) which projects from the base body on a second side thereof opposite the first side and which is configured to engage in a slot-shaped recess on the sink; in which an angle between an engagement direction of the anchoring part (4.1-4.6) and the direction of the spring force is at least 135 degrees, preferably at least 150 degrees, most preferably 180 degrees; in which the spring parts (3.1-3.8) are configured as tongues that project from the base body in an edge region of the base body and have a first partial extent (3.8a) adjoining the edge region and a second partial extent (3.8b) adjoining the first partial extent, the tongues extending in the first partial extent (3.8a) approximately perpendicularly to the base body and in the second partial extent (3.8b) approximately parallel, or at an acute angle of less than 45 degrees, preferably less than 30 degrees, to the base body; and in which the spring parts (3.1-3.8) have a further, third partial extent (3.8c) which adjoins the second partial extent (3.8b) and in which the spring parts (3.1-3.8) are angled away from the base body to a greater extent than in the second partial extent (3.8b); wherein the spring parts (3.1-3.8) differ from each other with regard to the angle between base body and tongue in the second partial extent (3.8b) and/or a length of the third partial extent (3.8c).
