Abstract

Releasable connection of a works-holding ring (1) to the centre part (2) of a non-circular clock housing, in which connection there are inserted in recesses (4) in the works-holding ring (1) fastening elements (7, 8) in each case having a shackle (7). When the connection has been carried out, the edges of each shackle (7) enter both into holding grooves (5) of the works-holding ring (1) and into an inner groove (16) of the housing centre part (2). For the purpose of bringing about a predeterminable closing pressure, each shackle (7) is constructed as a non-rotatable spindle nut having a spindle thread (10) extending over less than 360 DEG , the said thread being limited at both of its ends by a respective stop (12, 13). Cooperating with the spindle thread (10) is a rotatable closure piece (8) which forms together with the shackle (7) the fastening element (7, 8) and has a radially protruding cam (14). <IMAGE>
