Abstract

There is provided a device for fastening a connecting member to a handle of a cooking vessel; the connecting member has a collar portion having an inner cavity into which a connecting portion of the handle is inserted; the collar portion is bounded by a lateral wall closed into a loop by means of two opposite end tabs joined to each other and defining at least one preassembly tooth cooperating with a seat formed in the connecting portion; and the connecting member has a fastening member, which is pressed and permanently deformed inside a recess on the connecting portion to secure the connecting portion inside the cavity.

the connecting member (3) fitted onto connecting portion (6) so that an end edge (25) of the collar portion (20) substantially perpendicular to the axis (A) rests against an axial shoulder (10) of the handle (2);
the preassembly tooth (37) inserted inside the seat (15) to cooperate with and rest against a retaining surface (45) of the seat (15), the retaining surface (45) disposed opposite the shoulder (10) and extending substantially perpendicularly to the axis (A) so as to face the end edge (25);
the lateral wall (30) of the connecting member (3) comprising at least one slit (40) extending along and in the direction of a curve of an outer surface (36) of the lateral wall (30) of the collar portion (20) and crosswise to the axis (A) on the outer surface (36) and defining a sector (39) of the connecting member (3), in turn defining a press-in fastening member (38) for securing the connecting portion inside the cavity;
the fastening member (38) bounded by at least one slit (40) being pressed and deformed permanently inside a recess (16) formed on the connecting portion (6);
the preassembly tooth (37) and the fastening member (38) being located on opposite sides (41, 42) of the collar portion (20) of the connecting member (3), and the seat (15) and the recess (16) being located on respective opposite faces (11, 12) of the connecting portion (6).

the connecting portion (6) comprises two opposite faces (11, 12) having, respectively, a seat (15) and a diametrically opposite recess (16), both formed in the connecting portion (6);
the seat (15) having a retaining surface (45) extending substantially perpendicularly to the axis (A);
the connecting member (3) also comprises a permanently deformable, press-in fastening member (38) for securing the connecting portion inside the cavity, defined by a sector (39) of the lateral wall (30) bounded by one or more slits (40) formed through lateral wall (30) so as to extend along and in the direction of a curve of an outer surface (36) of the lateral wall (30) of the collar portion (20) and crosswise to the axis (A);
the preassembly tooth (37) and the fastening member (38) being located on opposite sides (41, 42) of the collar portion (20) to engage the seat (15) and the recess (16) respectively;
the preassembly tooth (37) inside the seat (15) cooperating with and resting axially against the retaining surface (45) of the seat (15).
