Needle for inserting an object into the body

A process for the production of a split cannula (10), and such a cannula having predetermined break lines (18) which run in the lengthwise direction (12) and preferably are diametrically opposite, are proposed, with the predetermined break lines (18) being produced by non-metal-cutting shaping.

Split cannula and process for the production thereof

A latch is known for a laboratory apparatus, for locking a cover or door on its housing, having a hook 12 in one of the parts to be locked and a lock 1 in the other. The lock has a pivotable locking element 3 with a claw-shaped opening 9 which engages the hook 12 against the pressure of a spring and is releasable from engagement with the hook by an actuating element 7. In order to provide a latch of this kind with means to meet strict safety requirements and ensure secure locking during operation of the apparatus, an additional closing element 4, opening element 5, and securing element 6, which engage one another, are disposed between the locking element 3 and the actuating element 7.
