Abstract

The invention relates to a support or leg (1) provided with a levelling member. The support or leg consists of a rod-like member (3) which can slide in an opening arranged in the support or leg and arresting means for arresting the rod-like member. The arresting means consist of a tongue (4) which is placed substantially perpendicularly of the rod-like member and which in a position of use allows a displacement of the rod-like member in one direction.
