Abstract: A plug (1) for a profiled safety edge section (2), comprising a first contact element for a first wire (3) of the profiled safety edge section (2), a second contact element for a second wire (4) of the profiled safety edge section (2), and an insertion nose (16), wherein the two contact elements are received in the insertion nose (16). The first contact element is a first support (8) with a first claw (9), and the second contact element is a second support (10) with a second claw (11).

Abstract: The invention pertains to a handheld pipette (11) with a handle (13), an interconnecting part (15) to attach a pipette tip and an ejection mechanism to remove the pipette tip from the interconnecting part (15). The ejection mechanism has a movable slider (43) relative to the interconnecting part (15) in the area of the interconnecting part (15 that is designed to slide the pipette tip from the interconnection part (15) when operating the ejection mechanism. The pipette (11) furthermore possesses a first and a second operating element (45, 47) accessible from the outside to operate the ejection mechanism, whereby the first operating element (45) is arranged in the area of the handle (13) and is operable by hand, and where the second operating element (47) is intended to be operated by an external device (71).
