The pair of crutches, or ski stocks, are held in a stable position when leaning against a wall etc. by a clip, which fastens the two crutches together. The clip (1, 2) has two grooves of U-shaped cross-section with the open part of one groove facing in the opposite direction to the open part of the other groove. The axes of the grooves are so aligned that they do not lie in a common plane. One crutch (3) of a pair is fitted into one groove, whilst the other one (4) is fitted into the other groove. ADVANTAGE - Easy handling.
