Fixation collar for fixing e.g. conduit on skirting board, has seat provided with cylindrical reinforcing ring, where dimensional ratio of height of reinforcing ring with respect to total height of trapezoidal base is in specific value

摘要

The collar (1) has a rectangular parallelepiped support base whose opposite side walls (1b) are prolonged for receiving curvilinear articulated strips provided with an anchoring and locking unit. The side walls of the support base extend in an upper part by two wall parts (1c). A trapezoidal base (1a) of the collar comprises a circular shoulder forming a seat that is provided with a cylindrical reinforcing ring (1m) to authorize the insertion of an anchoring unit. Dimensional ratio of height of the ring with respect to the total height of the trapezoidal base ranges from 65 to 75 percent.
