An arrangement for supporting a railing provided with a T-shaped groove and a slot communicating with the groove comprises a hollow supporting member and a T-shaped clamping element. The clamping element includes two clamping members each of which members has a first portion insertable in the hollow of the supporting member and a second portion insertable in the T-shaped groove of the railing. The clamping members are movable relative to each other in the longitudinal direction of the supporting member. The first portions of the clamping members are elongated in a direction of elongation of the supporting member, whereas the second portions are formed as pin-shaped projections each having an axis. The pin-shaped second portion of one of the clamping members is offset relative to the pin-shaped second portion of the other clamping member in a direction transverse to the axes thereof and to the elongation of the first portion. Means are provided for spreading the clamping members apart from each other so as to clamp the first portions in the supporting member and to clamp the pin-shaped second portions in the T-shaped groove of the railing. The spreading means include one or two screws extending through holes provided in one of the clamping members and abutting against the other clamping member. |
