<p>The equipment has a connection unit (3) including a central branch (10) and bent lateral branches (11) that are extended at the level of ends of the branch (10), on sides of the branch (10), respectively. The branches (11) are engaged on support surfaces (5) of anchoring units (2), respectively. The unit (3) is pivoted along an axis perpendicular to the branch (10) to slide the branches (11) along the respective surfaces till an interconnection position of the units (2). The branch (10) has ends that are situated at the proximity of the respective surfaces, in the position.</p> |
