PCT No. PCT/AT81/00002 Sec. 371 Date Oct. 9, 1981 Sec. 102(e) Date Oct. 9, 1981 PCT Filed Feb. 12, 1981 PCT Pub. No. WO81/02332 PCT Pub. Date Aug. 20, 1981.One or the female part of two releasably connected parts has a recess, cavity or the like, the second or male part is a couterpart insertable therein. Engaging elements are formed by at least one layer of elastic, vertically extending bristles, short fibers or the like, which are preferably electrostatically flocculated and engage on an uneven counterface. The face or faces provided with elastic bristles or the like as well as the counterface or counterfaces extend parallel to the moving directions of the two parts. In a preferred embodiment, the uneven counterface is a second layer of elastic, vertically extending bristles, short fibers or the like. During displacement in one direction, the bristles are moved into inclined positions and have to follow every change of direction. Thereby, a resistance has to be overcome, the resistance reaching a maximum in a change of direction of 180 DEG , i.e. a reverse of direction, but being adapted to be overcome without damaging the bristles according to the invention. Hence, a continuous locking of the two parts without requiring additional locking devices as well as a repeatedly releasable and restorable connection is obtained.
