The sleeve is of a length to project beyond relation, which device is releasably maintained both ‘portions M and I5 and has at one end a in assembled position with the parts for quick pair of diametrically opposed slots l9 and 20. attachment thereto and detachment therefrom. A member 2| is positioned within the sleeve l8‘ It is well known to provide a construction for in a relatively close ?t'and is bifurcated or slotted joining parts that involves a pin-like structure from its right end as viewed in Fig. 1 to a region extending through them for holding them to or left end portion 2|a so as to be provided with gether.

This variation in the thickness of the legs M and 42 provides a constant strength section for these legs. The pin When it is desired to withdraw the pin 11 from the openings in the attaching portions I 4 and I5 and the ‘part I6, a ?nger is inserted in the opening 33 in the control element 29, and the control element is shifted angularly to bring the of Figs. 6 and '7 has a control means 44, which ?anges 31 into contact with the left end of the 30 is formed of a single piece 45 having a ?nger sleeve I8, as seen in Fig. 2. This necessitates a opening 46 and a washer 41, surrounding the left shifting of the member 2 I 'to the left with respect end of the member 39 and positioned between to the sleeve I3, causing the ends of the legs 22 the piece 45 and the left end of the sleeve I6 and 23 to be moved inwardly toward one another so as to prevent entrance of an arcuate portion because of sliding of the cam portions '24 of the .35 '48 in the left end of the sleeve I8. This portion legs 22 and 23 along the bases Of the slots ‘I9 connects two straight portions 49 and 50 gen and '20.
