• the latching lug can accordingly still be connected to the stem wall on one side of the opening (the fourth side of the rectangle or trapezoid or the third side of the triangle).
• an end region of the locking lug that points towards the outlet can additionally bend away, e.g. claw-like, from the longitudinal axis, while, for example, the rest of the latch does not include such a bend.

• the straw element 80 comprises a straw wall 85, an inlet 83 to be placed in a beverage package with an inlet tip 84 and an outlet 81 to be placed outside the beverage package.
• the straw element 80 shown has a round cross section 82 with a diameter and a longitudinal axis 86. Reference is also made to this
• the locking lug 87 comprises a first part 88, which is designed here, for example, as an open ring surface, an inner diameter of the ring surface being equal to or up to 10% smaller than an outer diameter of the stalk element 80, and a second part 89 which extends from the first part 88 and extends away from the longitudinal axis 86. Due to the difference in diameter, the locking lug can be elastically clamped onto the surface of the stem element 80.
• the inside diameter of the ring surface can also be up to 1% or 5% larger than the outside diameter of the stem element, the latching nose then having to be connected to the drinking straw with additional measures such as welding, sealing or gluing.
• the first part 88 is designed such that it surrounds the circumference of the stem element 80 by more than half; it is possible to clip the catch 87 onto the stem element 80.
• the second part 89 is, for example, wing-like, but can also have other forms of a latch, such as any shape of a barb.
• the wing-like embodiment has the advantage that when the drinking straw is inserted into the beverage packaging, it bears against the wall of the drinking straw, thus making it easy to insert the drinking straw into the beverage packaging.
• FIG. 8C shows a drinking straw 90, the latching lug 87 from FIG. 8B being arranged on the straw element 80 from FIG. 8A.
• the latching lug 87 can be clipped onto the stalk element by means of the first part 88. It is also possible to use a liquid-resistant adhesive. Then the catch 87 can alternatively also be welded or sealed onto the straw element 80. In other embodiments, more than one locking lug 87 can also be arranged on the straw element 80.
• FIG. 8D schematically shows a second embodiment of a locking lug 91 produced by means of an injection molding process.
• the locking lug 91 comprises a first part 92, which is intended to be arranged with the outer surface of the culm wall 85 by welding or sealing, for example using a liquid-resistant adhesive .
• the first part 92 is designed such that it surrounds the circumference of the stem element 80 by less than half; it is therefore not possible to clip this first part 92 onto the straw element 80.
• the detent 91 comprises a second part 93, which extends from the first part 92 and extends away from the longitudinal axis 86.
• the second part 93 is wing-like remplibil det.
• FIG. 8E shows a drinking straw 94, the latching lug 91 from FIG. 8D being arranged on the straw element 80 from FIG. 8A.
• the first part 92 of the latching lug 91 can be connected to an outer surface of the culm wall 85 by welding or sealing. In other embodiments, more than one latching lug 91 can also be arranged on the straw element 80. It is also possible to arrange one or more latches 87 from the first embodiment and one or more latches 91 from the second embodiment on a straw element 80. It also applies to the locking lugs produced by means of an injection molding process that they have a distance from the inlet 83 along the longitudinal axis 86 of the stem element 80 of at most 30% of a length of the stem element 80.
• the length of the straw element 80 and the length of a drinking straw, which comprises the straw element 80 and one or more latching lugs correspond to one another, ie they are of the same size.
