1. A fastening assembly extending along a longitudinal axis, comprising: a cylindrical neck member comprising a series of convolutions axially extending around at least a portion of the external surface of the neck member and forming an interrupted helical thread of incomplete formation; anda collar member configured for screw fastening with the neck member, the collar member having an inner cylindrical surface comprising at least one rib configured for thread-engagement with the helical thread, the at least one rib forming a portion of an internal thread,wherein each convolution of the series of convolutions extends from a lead end to a brake end, wherein the brake end is spaced from the lead end forming therebetween a sliding gap constituted by the incomplete formation of the interrupted helical thread,wherein the brake ends of the series of convolutions extend in a parallel manner to each other and are interconnected by an arresting wall extending in parallel to the longitudinal axis, the arresting wall being configured for preventing threading of the at least one rib thereover,wherein the arresting wall extends radially outwards from the external surface of the neck member and projects at least to a height corresponding to the height of the convolutions, terminating at an edge, andwherein an inclined gliding surface is provided adjacent one side of the arresting wall, the inclined gliding surface extending from the external surface of the neck member and towards the edge of the arresting wall such that said at least one rib can jump over said gliding surface when threaded thereover. 2. The fastening assembly according to claim 1, wherein the sliding gap axially extends along at least a portion of the neck member parallel to the longitudinal axis. 3. The fastening assembly according to claim 1, wherein the at least one rib is configured for slidable displacement along the sliding gap which axially extends along at least a portion of the neck member parallel to the longitudinal axis. 4. The fastening assembly according to claim 1, wherein the neck member comprises at least two radially displaced sliding gaps. 5. The fastening assembly according to claim 1, wherein the at least one rib is configured for threading through the lead end of any one of the convolutions. 6. A container system having a longitudinal axis passing therethrough, comprising: a receptacle member comprising a cylindrical neck member, comprising a series of convolutions axially extending substantially along and around at least a portion of the external surface of the neck member and forming an interrupted helical thread of incomplete formation; anda closure member configured with a collar member for fastening over the neck member, the collar member configured for screw fastening over the neck member, said collar member having an inner cylindrical surface comprising at least one rib configured for thread-engagement through the helical thread, the at least one rib forming a portion of the internal thread,wherein each convolution of the series of convolutions comprises a lead end and a brake end, such that the convolution extends from the lead end to the brake end, wherein said brake end is spaced from said lead end forming a sliding gap constituted by the incomplete formation of the interrupted helical thread,wherein the brake ends of the series of convolutions extend in a parallel manner to each other and are interconnected by an arresting wall extending in parallel to the longitudinal axis, the arresting wall being configured for preventing threading of the at least one rib thereover,wherein the arresting wall extends radially outwards from the external surface of the neck member and projects at least to a height corresponding to the height of the convolutions, terminating at an edge, andwherein an inclined gliding surface is provided adjacent one side of the arresting wall, the gliding surface extending from the external surface of the neck member and towards the edge of the arresting wall. 7. The container system according to claim 6, wherein the rib is configured for slidable displacement along the gap. 8. The container system according to claim 6, wherein the neck member comprises at least two radially displaced vertical gaps. 9. The container system according to claim 6, wherein the at least one rib is configured for threading through the lead end of any one of the convolutions.
