Locking members 4 and 5 are provided which are suitable for mounting on a tapping box 1 such that in use they may secure said tapping box 1 onto a busbar or busbar trunking 3. The members 4 and 5 may be leg-like members with hook portions 4a and 5a. The members 4 and 5 may be part of a mechanism which moves in a clutching or releasing manner. This mechanism may comprise an over-centre cam arrangement 8 and 9, link arms 6 and 7 and the members 4 and 5 with pins and slots 11-14 and 16-19. The mechanism may be operated by rotation of the cam 9. The cam 9 may also be linked with a lid interlock device 10 which restricts the operation of a lid 2.
