ABSTRACT:
A pipe clip having a hook closure for connecting a first part to a second parts. The first part is provided with at least one outwardly directed hook member and the second part is provided with at least one inwardly directed hook member. Each hook member has a hook surface and another boundary surface such that when the hook is closed the hook members move towards each other in the direction of closing and pass each other until the hook surfaces of the inwardly and outwardly directed hook surfaces engage behind each other. In the closed position the boundary surfaces of the hook members hooked behind each other rest against each other. Each hook member is further provided with a locking facility such that when the hook is closed, mutual lateral shifting of the hook members is blocked. Each hook member is made of hook member halves lying side by side and adjoining each other. The halves are staggered slightly relative to each other so that each hook member half forms a hook surface half, and a first stop surface of the hook member extends between the hook surface halves situated staggered relative to each other. Each hook member half forms a boundary surface half, and a second stop surface of the hook member concerned extends between the boundary surface halves situated staggered relative to each other. When the hook is closed the stop surfaces block mutual lateral shifting of the hook members.
