The base member and the locking member include corresponding arcuate projections which engage when the locking member is in the locked position. The indicator includes a pair of engagement surfaces which engage when the locking member is in the locked position. In one embodiment, the engagement surfaces are provided by a projection on the locking member and a first recess and a second recess in the support member, and the projection extends into the first recess when the locking member is in the locked position.
