Abstract: A mounting device for bearings placed on shaft extensions consists of a lower support basin rigidly connected with the frame and of a lid, connected in a pivoting manner with same, provided with a lower lever forming the operating portion which, when the lid is in the open position, extends into or across the support basin far enough to pivot the lid into its closed position by lowering the bearing abutting against it and placed on the shaft extension; in which closed position the basin rests tightly against the bearing with its circular, curved inner side. For the sake of simplification, a single lid is provided in a pivoting manner with a locking lever, which has at its end a hook portion, which engages an abutment of the support basin. Furthermore, an arrangement is provided which automatically pivots the locking lever.

Abstract: A connector pair with a plug (1) and a receptacle (1'), each of which comprises at least one contact insert (7, 7') in which at least one contact (9, 9') is arranged, whereby free ends (13, 13') of the housings (3, 3') can be joined in such a manner that the free end (13) of the other housing (3) projects into the open inner space (14') on the face of the one housing (3') and the contacts (9, 9') of the plug (1) and the receptacle (1') come into engagement with each other, is adapted such that in the area of the free end (13) at least one recess (17) is provided in an outer wall of the one housing (3), in the area of the free end (13') of the other housing (3') at least one engaging element (20) corresponding to the recess (18) is provided, which in a first position projects into the inner space (14') of the other housing (3') and in a second position clears the inner space (14') of the other housing (3'), and that a sleeve (30) surrounding the free end (13') is arranged, which in a rest position urges the en
