ABSTRACT:
A tubular device which is anchorable to a plate member comprises a first part including a tubular sleeve having resilient legs formed on one end thereof and an annular flange separating the legs from the rest of the sleeve and a second part comprising a tubular actuating member received in the sleeve. The tubular actuating member has a tapered end adjacent the legs. The tubular device is adapted to be received in a bore through a plate member whereupon the actuating member may be urged into engagement with the legs whereby the actuating member spreads the legs, causing the plate member to be gripped between the legs and the annular flange. The actuating member may be left in engagement with the legs, thereby to hold the legs in the spread configuration. Alternatively, after the tubular device is placed in a bore through a plate member, an elongated member which is to be fastened to the plate member by means of the tubular device may be inserted into the tubular device through the end of the sleeve remote from the legs and used to push the actuating member out of the sleeve through the other end of the sleeve whereby the actuating member spreads the legs, causing the plate member to be gripped between the legs and the annular flange.
