At least one resilient male part (8) in the tool part (2) is received by a seat (7) in one end of the shaft (1). A side opening (16) in the seat receives a relatively thick section (14) of the male part, which acts as a catch. Normally the catch is in contact with a seat surface (20) adjacent to the side opening, but application of pressure to the opening will cause the catch to be released from the seat. |
