#CMT# #/CMT# The fastener (1) has barbs (10, 11) produced by inclined cut-away portions starting from edges of an intermediate portion of the fastener. A lateral wing (6) includes an anti-recoil stop that is intended to bear against a complementary abutment surface. The anti-recoil stop is produced by cutting out and deformation of a tongue from the lateral wing. Symmetrical lateral wings start from limbs of the intermediate portion of the fastener. The cut-away portions in shape of the barbs extend in prolongation of the wing and in direction of the intermediate portion. #CMT#USE : #/CMT# Used in automobile industry for fixing two parts of equipment of a vehicle. #CMT#ADVANTAGE : #/CMT# The cut-away portions in shape of the barbs extend in prolongation of the lateral wing and in direction of the intermediate portion, thus locking the barbs for locking the intermediate portion of the fastener on one part of the equipment, and hence reliably holding the barbs in position in another part of the equipment. The lateral wing includes the anti-recoil stop that is intended to bear against the complementary abutment surface, thus improving the resistance of the fastener to tearing-off. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows an assembly position of a fastener. 1 : Fastener 3, 4 : Limbs 6, 7 : Lateral wing 6a, 7a : Elbow portions 10, 11 : Barbs. |
